Eukaryotic cell cycle Flashcards
1
Q
G1 phase (3)
A
- Cytosol volume increases
- Synthesizing proteins
- Replicating organelles
2
Q
G0 phase
A
For cells that are not required to replicate such as quiescent cells which can re-enter cell cycle or terminally differentiated cells which cannot re-enter cell cycle
3
Q
S phase (2)
A
- Replicates DNA
- Turns chromosomes to sister chromatids
4
Q
G2 phase (2)
A
- Increasing cytosol volume
- Synthesizing proteins
5
Q
G1 checkpoint (2)
A
- Verifies the cell has grown to the correct size
- Checks if cell has synthesized enough proteins
6
Q
G2 checkpoint (2)
A
- Checks if DNA replication has been done properly
- Checks if the cell has enough resources for mitosis
7
Q
Prophase (4)
A
- Nucleolus disappears
- Chromosomes condense
- Spindle fibers are formed
- Nuclear membrane breaks down
8
Q
Metaphase (2)
A
- Spindle fibers fully form
- Chromosomes gather at the center of the cell
9
Q
Anaphase (1)
A
Chromosomes are pulled to opposite ends of the cell
10
Q
Telophase (3)
A
- New nuclear membrane forms
- Chromosomes decondense
- Spindle fibers disintegrate
11
Q
Cytokinesis (2)
A
- Cytoplasm divides
- Creates daughter cells
12
Q
Cytokinesis: Animals v Plants
A
In animals, cleavage furrow develops pinching the cell in half whilst plants develop a cell plate.
13
Q
Metaphase checkpoint (2)
A
- Checks formation of spindle fibers
- Checks if chromosomes are in right location
