Lab 1 Flashcards
Cell Cycle & Mitosis
1
Q
G1
A
- Cell increases in size
- 2C DNA per cell
- one-chromatid chromosomes
2
Q
S
A
- DNA copied
- 4C DNA per cell
- two-chromatid chromosomes
3
Q
G2
A
- centrosomes opposite side nucleus
- 4C DNA
4
Q
Prophase
A
- chromosomes condense
- 4C DNA
- mitotic spindle fibers form
- microtubules grow & arch
5
Q
Prometaphase
A
- nuclear membrane breaks down
- 4C DNA
- spindle fibers connect to chromosomes @ kinetochore
6
Q
Metaphase
A
- chromosomes line up middle
- 4C DNA
7
Q
Anaphase
A
- adhesive protein @ centrosomes dissolved
- 4C DNA
- chromatids pulled apart
8
Q
Telophase
A
- nuclear membrane forms around both groups of single-chromatid chromosomes
- 4C DNA
- chromosomes decondense
- spindle apparatus disappears
9
Q
Cytokinesis
A
- cell divides into two new cells
- 2C DNA
10
Q
3 major events in cell cycle
A
replication, segregation, division
11
Q
Kinetochore microtubules
A
used for moving
