1 Biol 14A: Genetics and Genomics Fall 2016 Dr. Rachel Woodruff Introduction Think for a moment about inheritance. What did you get from your biological parents? What do you know about your own genome? The fields of genetics, genomics, and molecular biology have been developing rapidly over the last few decades: PCR, gene cloning, anti-retroviral therapy, next-generation DNA sequencing, RNAi, somatic cell nuclear transfer (animal cloning), induction of pluripotent stem cells, CRISPR to name but a few advances! We can expect these fields to continue to advance, and to affect more and more aspects of our lives. How will doctors use their patient s genomic information in a few years? What discoveries will alter our fundamental understanding of molecular biology? How will genetic engineering be adapted to cope with global warming? The super-goal of this course is for you to be able to understand and interpret such new developments and applications, as they affect your own life and career, throughout your life. The Learning Goals for this course encompass the skills and knowledge that will enable you to interpret past, present, and future findings in genetics. These are the large goals we will work toward all semester: - You should have a conceptual understanding of the molecular mechanisms that result in phenotypes and biological inheritance. If you have a strong framework of understanding what the key components and processes are, you will be able to use this to interpret new information. - You should understand many of the common tools and approaches currently used by researchers in genetics, genomics and molecular biology. If you understand how these approaches work, and how they are interpreted, you will be able to understand how they have been used to reach new conclusions, and you will also be better equipped to figure out experimental approaches that are unknown to you. - You should know strategies and information sources you can use to make sense of new observations relating to molecular biology or genetics. When you have met these goals, you will be ready to begin being an informed reader of primary research articles in the field. You will be able to question and discuss experimental

2 results and interpretations. Some of you will go on to use these skills and concepts to become researchers, creating the future of the field; and all of you, I hope, will use them to be betterinformed voters and advocates for yourself, your families and your communities. Course structure Schedule: A typical week in BIOL 14a Like any 4-credit course, this should take you about 12 hours per week, including class time (4 hours, in this case) and out-of-class time. Success in this 4 credit hour course is based on the expectation that students will spend a minimum of 9 hours of study time per week in preparation for class (readings, papers, discussion sections, preparation for exams, etc.). There is some variation, but a typical week includes: - Readings: I recommend that you take time to read the week s readings ahead between and Monday. This is also a great time to do your Self Test (see below) - Monday Homework: one Self Test homework assignment to help prepare you for upcoming classes (online, through LATTE or the textbook LaunchPad site), due on Mondays - Lecture: three 50-minute Lecture meetings (all 225 of us), Mondays, Wednesdays and s 9:00-9:50 a.m., in Gerstenzang 123, which will be used for lecture, discussion, a Wednesday Question Session, of your questions, - Recitation: one 50-minute Recitation meeting, often including a Practice Quiz (smaller groups). Recitation sections and the activities you do there are an integral and required part of the course. - Daily Homework: several hours of reading, study, and work on Practice Problems, - Wednesday Homework: one Weekly Response assignment (online, due Wednesdays). - Testing: Some weeks will include Quizzes (given on s, approximately every other week). Some weeks will include additional homework ( special assignments ), which are sporadic. You will get the most out of this class if you come to both lectures and recitations prepared to actively engage in thinking, questioning, and problem solving. By its nature, the material you will learn in this course is all inter-related. It will not be presented in separate units with breaks in between, but will be presented in a continuous format. That means, for example, that we will continue working on new material right up until each quiz, though quizzes will not cover the last couple of days of newest material. On attendance: You should attend every class. I know that everyone has extenuating circumstances sometimes, but if circumstances make you miss class more than 3 times during the semester, you may have overextended yourself, and you should consider dropping the class. Lecture meetings are not just for traditional listen-and-take-notes lectures. On some days (usually Wednesdays), we will spend part of our 50-minute meetings in Question Sessions in which you will work, often in groups, to answer and ask questions related to current course material. These sessions are intended to give you supervised practice in applying the concepts you are learning, which really is the hardest aspect of this course. Your work in Question Sessions will be graded based on your effort and participation.

3 Every, we will also have a portion of lecture explicitly devoted to Review. Exactly what we review will be up to you: part of your Weekly Response homework will be to describe your current confusions and questions about the material, so that your instructors can choose the most helpful things to spend more time reviewing. Recitation groups meet weekly, and are led by TAs who have research experience in genetics or related fields. It is important that you attend the recitation section you are registered for. You registered for one of these on SAGE when you signed up for the class: Section 1: Mondays, 5:30 6:20 pm Section 2: Mondays, 6:30 7:20 pm Section 3: Mondays, 7:30 8:20 pm Section 4: Mondays, 7:30 8:20 pm Section 5: Tuesdays, 5:30 6:20 pm Section 6: Tuesdays, 5:30 6:20 pm Section 7: Tuesdays, 6:30 7:20 pm Section 8: Tuesdays, 7:30 8:20 pm Section 9: Mondays, 4:30 5:20 pm How will recitation time be used? They will be a mix of practice and review. Many recitation section meetings will include a Practice Quiz. These are much shorter than the Quizzes given as assessments during lecture, but they will be composed of questions similar to those you ll see in the actual Quizzes. Unlike the Quizzes themselves, you will work through these Practice Quizzes in groups. This will help you to learn from and teach each other, and to gain experience in discussing genetics concepts. Part of each recitation section will also be devoted to review, primarily focusing on concepts you have raised in your Weekly Response or in s to your TA, or on new questions you raise. It is fine to your TA over the weekend, with questions you d particularly like them to go over in section. Of course, you can also ask questions in class on the spur of the moment. Homework will be listed in the course schedule on the course LATTE site. You should expect to spend about 8 hours each week in homework and studying for BIOL 14a. There are five types of homework assignments. Readings are primarily from the textbook Biology: How Life Works (edition 1 or 2). You should read each reading assignment before the class date it is associated with, and may also need to review it after lecture. Practice Problems are posted as PDFs on LATTE. Doing these problems is essential to success in the course. They are similar to those you will see in Practice Quizzes, Quizzes, and the Final Exam. You are responsible for doing all the practice problems, as they are posted, but you will not hand these in for grading. Answer keys will be posted on LATTE to allow you to check your own work. Weekly Responses are online questions you will answer each week (by 3pm Wednesday). These are graded credit/no-credit, based on whether you put in thoughtful effort in answering the questions. If you are keeping up with your other work, they should not take you long to answer. Here, you will communicate your interests and confusions to instructors, so that we can adapt course content accordingly. You are expected to complete at least 9 of these responses over the course of the semester. Note that there will be 14 opportunities, so you can miss 5 of them, but keep track so you don t miss more!

4 Self Tests are on-line assessments, composed of sets of basic questions. Though each has its due-date, you can start on them as early as you like. These are intended to help you test your own reading comprehension to prepare for upcoming activities in class. These questions typically are not representative of the types of questions you ll see on Quizzes. They are graded for correctness, but most questions allow you multiple tries, so you really ought to aim for getting 100% on every Self Test. Self-tests will be administered through LATTE or the textbook s LaunchPad site. Special Assignments are occasional other assignments, such as the chat-group meetings, and journal club preparation. They are not regularly occurring, but are graded. Resources: Course website: Essential resources are posted for you on LATTE. Check the course website on LATTE frequently for course announcements, lecture notes, assignments, practice problems, and answer keys, as well as updates to the course schedule. In addition, you will find it helpful to sign up for the course Q&A forum on Piazza (the link will be available through LATTE). This is a place where you can ask questions, and likely receive a faster response than if you Dr. Woodruff directly. You can also see what questions other students have asked (anonymously), and what answers they received from instructors. Office Hours: Please come! Dr. Woodruff and every TA have weekly office hours listed at the top of the course LATTE page. Even though you have one recitation TA, you may attend any one s office hours. You are also welcome to set up appointments with us outside of office hours if needed. Textbook: Morris: Biology, How Life Works. either 2 nd or 1 st Edition. Reading assignments are listed on the syllabus and on the course LATTE site. It is expensive, but you can use it for BIOL15 and BIOL16 as well! The textbook will be a very useful reference for you; however, there will not be an exact correlation between topics covered by the textbook and topics covered in class. Use the textbook as a reference, but use the practice problems, recitation activities, and lectures as the defining resources in your studying. The textbook also comes with an online resource, LaunchPad. If you have purchased a version of the book that includes LaunchPad, you ll be able to use this site for reading and reviewing textbook material. In particular, I have assigned specific LearningCurve Self Test which you can do, instead of Self Tests on LATTE. It is not required that you have LaunchPad access; however, if you bought LaunchPad access for the first edition of the textbook, you should still be able to access our course LaunchPad site, even though it is the 2 nd edition version. Learning Catalytics: This is a response system that we use to facilitate active learning and group activities, such as the Question Sessions, in lecture. Please buy a subscription for $12 for the semester (or $20 for the year) and use it in this class and any others that use this technology. You use it from your own device (smartphone, computer, etc). If you do not have an internet-enabled device, or if you think it will be too distracting to you to use it during class, please talk to Dr. Woodruff and we will make accommodations so that you can do the same activities without this tool.

5 Quizzes and Exams: Instead of midterm exams, we will have 5 shorter Quizzes, given in lecture, generally occurring on alternate s over the course of the semester. These are distinct from the Practice Quizzes which you will take in recitation sections: both are composed of similar types of problems to solve, but Quizzes have more problems than Practice Quizzes, and you must work alone on Quizzes. Quiz dates are given in the course schedule below. There are no make-up quizzes. Your one lowest quiz grade will be dropped. There will also be one cumulative Final Exam. Students with excused absences from the final exam will be able to take a make-up final exam next semester. (By design, the Quizzes ask you to solve a lot of problems in a short time-frame. Those of you who find this stressful will appreciate that the final exam is different: you should have more than enough time to complete the final exam.) Disabilities: If you are a student with a documented disability on record at Brandeis University and wish to have a reasonable accommodation made for you in this class, please contact me during the first week of class. Cell phones and laptops should only be used in class when they are part of a classroom activity. Use common sense, and don t waste your class time trying to multitask. If your use of a phone or laptop is perceived as disruptive by anyone in the room, you will be asked to put it away or to leave. Academic Integrity: For goodness sake do not cheat! It can only harm your education. You are expected to be familiar with and to follow the University s policies on academic integrity (see ). Faculty may refer any suspected instances of alleged dishonesty to the Office of Student Development and Conduct. Instances of academic dishonesty may result in sanctions including but not limited to failing grades being issued. Preliminary Course Schedule: The specific order and content of lectures and readings is subject to change. However, Quiz dates are set! Notes: 1) assigned readings should be done before the day of class they are listed with. Date Daily Topic Readings to do before this meeting, and assignments due this day. Aug 24 No class, but get ready! Read course Syllabus and LATTE page. Sign up for Learning Catalytics before first class meeting! Weekly response 1 due by 3pm.

When I was in college, I almost majored in Chemistry and History before choosing Molecular Biophysics and Biochemistry halfway through my Junior year. Ironically, I never took genetics as an undergrad! Now, I have been teaching at Brandeis for 4 years, and have taught genetics here 6 times (not including this semester). I love teaching here. Every semester, I learn more from my students. In addition to teaching, I like to play with my 2 young daughters, ride my bikes (only one at a time), and drink an excessive amount of tea. I hope you will come to my office hours and help me put a face, and a story, to your name this semester.
