week of 2 February - animations to help with class on Thursday

Hi everyone,

  Well, another week, another snow storm and yet more time we're missing!  Glad we're not there today as it is bitterly cold and the roads are bad.  Anyway, I'll explain how things will be modified via the blog after I chat with Mrs. Harder and Mrs. Magnuson tomorrow.  We'll still be doing the cell lab in class tomorrow.

  Thursday (week is now A, B, Ax, Bx) we'll talk about the cell cycle and DNA replication.  I am linking several animations below and highly suggest that you view these a couple of times before we meet Thursday as well as reading the relevant sections in the book.  I am going to go fast with the assumption that I am reviewing what you've already studied on your own.  Keep track of questions/areas of confusion so you can ask in class!

  Feel free to come to AFT both Thursday and Friday to work on the cell lab.  It is NOT due Wednesday, will determine the new due date after conferring with the other teachers.

  See you tomorrow, Ms. L

ANIMATION LINKS:

NOTE:  for both of the cell cycle animations, don't worry so much about the names of stages of mitosis (prophase, etc)...rather focus on what is happening with the chromosomes

Cell Cycle animation (mitosis)

Cell Cycle animation (mitosis) -- another version -- this does a nice job showing how DNA becomes chromosomes

DNA replication (+ some cell cycle & DNA wrapping)  -- please note there is terminology here that you are not responsible for (e.g. Okazaki fragments)

DNA replication in real time (some overlap with other at beginning) -- note -- stop at 3:21 as after that it is the protein synthesis stuff you've already seen
