Q
CDK binding sequence?
A
4,6. 2. 2,1. 1
6
Q
During Prophase?
A
Nucleolus disappears, centrosome divides. Astral rays and spindle fibers develop.
7
Q
What happens in metaphase?
A
Chromosomes align at center of the cell, nuclear envelope disappears
8
Q
What happens in anaphase?
A
Chromatids migrate to opposite poles, cleavage furrow forms
9
Q
What Happens in telophase?
A
cleavage furrow deepens, chromosomes uncoil
10
Q
What does Vincristine do?
A
Prevent spindle fiber formation
11
Q
What does colchicine do?
