Phases of Mitosis Flashcards
Cell Cycle
1
Q
Interphase
A
The period of the cell
cycle when the cell is not dividing
2
Q
Mitosis
A
The period of the cell
cycle when the cell is not dividing
3
Q
G1
A
- First growth phase
- Protein synthesis, organelles copy
4
Q
S (synthesis phase)
A
DNA duplication
5
Q
G2
A
- Second growth phase
- Protein synthesis, energy replenishes
6
Q
3 Phases of interphase
A
1.) G1
2.) Synthesis phase
3.) G2
7
Q
Chromatin
A
Loose DNA in the nucleus
8
Q
Centromeres
A
Mark a chromosome
9
Q
Sister chromatids
A
- Produced by DNA replication
- Connected by a centromere
10
Q
Prophase
A
- Nuclear envelope breaks down
- DNA condenses
11
Q
Centrosomes
A
Specialized organelles that act as tracts to pull the chromosomes apart
12
Q
Metaphase
A
- Chromosomes line up at the equator
- Spindle fibers appear and attach to the centromere of each chromosome
13
Q
Anaphase
A
- Sister chromatids are pulled toward opposite poles
- Cell begins to appear elongated
14
Q
Cleavage furrow
A
Contractile band of microfilaments that squeeze the two cells until they separate
15
Q
Telophase
A
- Sister chromatids arrive at opposite poles and begin to decondense
- Nuclear envelope begins to reform
- Mitotic spindle breaks down
- Cytokinesis
