Today we had a late arrival so we didn't have time to do much in class but we did check in our cancer graphs and got our stamp sheets stamped. We also took some notes on mitosis and had the rest of the class time to work on our mitosis color code which is homework if you did not finish in class.

Homework
Finish mitosis color code wit annotations due tomorrow.
Work on research for cancer project due on Monday, September 25

Mitosis Notes
G1- cell grows, normal functions of life

S phase- DNA and chromosomes are replicated

G2- cell grows and prepares for mitosis by making proteins and structures needed for division.

M phase- physical division of cell

- in interphase chromosomes appear as chromatin

- when mitosis begins chromatin condenses to form visible chromosomes

- sister chromatids are identical halves of a duplicated chromosome

our next scribe is Michael Ruderman
