Bio 121 Announcements

12/4/08    For the next reading about eukaryotic transcriptional control, you should look at Ch. 16, pp.320-322 on chromatin.  For the pages assigned today, you can skip the stuff on DNA Methylation and Epigenetic inheritance on p. 358.

11/25/08    The final time, date, and location have been announced.  Please inform me of any conflicts.

11/21/08    For Monday and Tuesday, we won't get to the entire reading.  Read pp. 337-342, about translation.  We'll talk about the rest of the reading after Thanksgiving.  I think I'll be able to do that and all of the mutation stuff on that day and be back on schedule.

11/20/08    I am allowing you to revise the written portion of Exam 3.  Please see the link in the syllabus, next to Exam3 for instructions on how to do this.

11/11/08    For the last lecture of this unit, add to your reading pp.301-302, inheritance of organelle genes.

11/6/08    For the lecture on the second half of Ch.14, do the problems suggested on the online syllabus.

11/3/08    For the Genetics lectures, there are genetics problems that I suggest that you do on your own.  This is the kind of thing I'll have on the exam.  For today's reading, try questions 2, 3, 5, 6 at the end of the chapter.

10/30/08    For the next reading (meiosis), you can skip the material on page 252 "The Variety of Sexual Life Cycles).  I will breeze through the material in pp. 248-252, so look at the specific terms and concepts I cover and read the rest only for your own information.

10/22/08   For chapter 11, read pp. 206 - 217 (NOT including Fig. 11.7 - Exploring Membrane Receptors).  Only read through cyclic AMP, we won't do calcium ions and IP3.  Also read page 221.

9/22/08    Just a heads up, the finals schedule has been announced.  Our final is Wednesday, Dec. 17th, 8AM -10AM.  This is now on the online syllabus too.

91208    I am changing the reading a bit for the next reading, the one about cells.  I will still cover the first part (including the nucleus).  I'll then skim over the rest of the endomembrane system (endoplasmic reticulum and Golgi, pp. 102-106) and I'll get back in detailed coverage with p. 107, the lysosome and the vacuole.  I will NOT cover the material in p. 109-111 (mitochondria, chloroplasts, peroxisomes).  Instead, I'll cover that when we talk about cellular respiration and photosynthesis.

9/4/08    For the next reading (Sept 8/9), I am adding just a bit to it.  I will talk about isomers, in particular enantiomers, briefly, so skim over that section (p. 62) and look at figure 4.7(c) and 4.8.  I'll also talk a bit about functional groups, so look at p. 63 briefly and on p. 64 look at the hydroxyl group.

9/3/08    OK, more info about web site.  I have learned that you don't need the course ID to use the "Study Area" of the web site.  You only need the course ID if I put quizzes and homework on that website, which I have no plans to do.  So, just use your login and password, and you should be able to get to everything you need.  Thanks for being patient!

9/2/08    I know that you cannot register an account in the books web site for this course.  I have changed a setting in the web site, try it again using the course ID MBREAGAN07331 and let me know if it works now.  Thanks for being patient, these are the issues when we get a new book.
