Bio/BioChem The Cell Cycle Flashcards
1
Q
Interphase
A
- G1
- S
- G2
- longest phase of the cell cycle
2
Q
G0
A
cell is living and serving its function with no preparation for division
3
Q
Chromatin
A
less dense chromosomes
4
Q
G1 stage
A
- presynthetic gap
- creation of organelles for energy and protein production
- increase in size
5
Q
Restriction point
A
governs cells going from G1 to S
6
Q
S stage
A
- synthesis of DNA
- replication of genetic material to produce chromatids
- have 2x the DNA
7
Q
G2 stage
A
- postsynthetic gap
- quality control checkpoint
8
Q
M stage
A
- mitosis
- cytokinesis
9
Q
p53
A
protein in control of cycle control checkpoints
10
Q
Mitosis
A
- prophase
- metaphase
- anaphase
- telophase
- cytokineses
11
Q
Prophase
A
- chromosomes condense
- spindle forms
12
Q
Metaphase
A
-chromosomes align
13
Q
Anaphase
A
-sister chromatids separate
14
Q
Telophase
A
- spindle disappears
- new nuclear membranes form
15
Q
Cytokinesis
A
separation of the cytoskeleton and organelles so that each daughter cell has enough to survive
