Last update 01/09/2017

This is a brief overview. Go to Courseworks or to http://www.columbia.edu/cu/biology/courses/c2006/

for links to expanded versions with all details. See 'About UN2006' or 'About UN2402'

COURSE DESCRIPTION: Biology UN2006/UN2402 is the second term of a one year introductory course for science majors, premedical students and engineering students. Bio UN2006/UN2402 covers selected topics in cell biology, developmental biology and physiology. Students in this course should have completed Bio UN2005/UN2401, or the equivalent, with a grade of C- or better. (D acceptable for SEAS students only.) Undergraduates in CC, GS & SEAS should enroll in UN2006.   All other students must enroll in UN2402. Note that there are 2 sections of UN2006 so that you can still enroll if you have a course conflict with the morning lectures. Any exceptions to any of the rules on this page must be approved by Dr. Mowshowitz, the sooner the better.

: The lectures in UN2006 and UN2402 are identical, and are given twice a day, morning and afternoon. Students in either course may attend either set of lectures. (You may register for one time and attend the other time if you have a course conflict, oversleep, or just can't make it.)
        Morning lectures:  10:10 - 11:25 am, Tuesdays & Thursdays, 417 IAB
        Evening lectures:   4:10 - 5:25 pm, Tuesdays  & Thursdays, 309 Havemeyer.

: The recitations for the two courses are separate. UN2006 students may not attend UN2402 recitations or vice versa. 
  UN2006 Students:  Students registered for UN2006 must attend one of the required UN2016 recitations. These recitations include a weekly quiz -- that's why UN2006 is 4 points.  Recitations start the second week of classes on the first Monday of the term.  Please sign up for recitation (UN2016) through the registrar as soon as possible. The times & places are posted on the  DOC (Dir. of Classes).
  UN2402 Students:   UN2402 is a 3 point course, and recitations are optional.  Students registered for UN2402 who wish to attend recitation may go to any of the UN2402 recitations; no sign ups are necessary. (Rooms & times will be posted on the web site, and recitations will start 1/24/17. Times will be similar to last term.) Students in UN2402 are urged to form study groups, especially if they cannot attend recitation.

There will be three midterm exams and a final.  The lowest midterm grade will be dropped. The midterms for both classes are given at the same time, in the late afternoon (4:10) or evening (probably 6:10 or later). Exact times will depend on room limitations, and will be published as soon as possible. Students with conflicting classes may take the exams at the 'other' time. If you have a time conflict with both exam times, please email Amanda, am4492@columbia.edu  as soon as possible. Exam days are listed on the home page and the schedule; be sure to check them before making travel plans.  

: The grade for the course is based on the best 2 midterm exams & the final exam, plus recitation points for UN2006 students. All details are on the web site. See 'About UN2006' or 'About UN2402'.) The grading scale for both courses is the same (except for the points earned in recitation) -- it is set by the undergraduate students in UN2006 and then the UN2402 grades follow the same scale. Note that the test scores earned by the post bacs do not affect the grading scale; there is no advantage to be gained (gradewise) by taking "the other" course.
A few "extra credit" points may be earned at the SURF symposium. The symposium is Feb 10, 2017 -- don't miss the opportunity!

COURSE WEB SITE: The Course web site is on Courseworks. You can also reach it from http://www.columbia.edu/cu/biology/courses/c2006/
    Access to the web site is required. All details of schedules, reading assignments, exam dates, announcements made in class, answers to exams & review questions, and class handouts will be posted on this website. Answers to students will be posted on Piazza (reachable from the web site).

Office Hours

Dr. Mowshowitz

Tues  &  Thurs. 2-3 or by appt., in 744D or 744E in Mudd. (Or after class.) Email or call to make an appointment.

BOOKS: All books should be on reserve in the Science Library in the Northwest Corner Building. Details on readings are posted on course website. Note that many students feel that it is NOT necessary to purchase anything but the Learner's Manual, aka, the problem book (#4). The texts are the same as last term, but the Learner's Manual is different.

1. Sadava, et al, Life, The Science of Biology, 10th ed, Sinauer, 2014. This is the text used in the first term, but you can find the same material in any of the general biology texts on the market. If you already have a different standard bio text, or an earlier edition of Sadava/Purves, you do not need to buy this one.
2. Hardin & Bertoni,  Becker's World of the Cell, 9th ed, Benjamin Cummings, 2016. Same text as first term. 8th ed (Hardin et al) is also okay.
3. A recent edition of a physiology book is recommended if you want to go into physiology in more depth or plan to take physiology later. We recommend Sherwood, Human Physiology: From Cells to Systems, & Silverthorne, Human Physiology:An Integrated Approach (the text currently used in the 3000 level course).  Any recent edition of these texts or any other decent physiology book will do too.
4. Mowshowitz, A Learner's Manual: Problems in Cell Biology, Physiology & Development, 11th edition, revised 2017. When the manual is ready, it will be available at the Village Copier on Amsterdam near 118th St. You do NOT need this book in advance. Please do not pester the Village Copier. We will tell you when the manual  is ready.
