2
Q

A
Chromosomes
3
Q
What types of eukaryotic cells undergo mitosis?
A
Single celled and multicellular
4
Q
What types of prokaryotic cells undergo mitosis?
A
Asexual and somatic cells
5
Q
What happens in interphase?
A
G1 (Gap)- Cell grows
S (Synthesis)- DNA is replicated
G2 (Second Gap)- Preparation for division
6
Q
What happens in prophase?
A
- Chromosomes condense
- Centrioles start to move to opposite poles
- Nuclear envelope breaks down
7
Q
What happens in metaphase?
A
- Homozygous chromosomes align on the cells equator in a single file line
- Spindle fibers attach at centromeres
8
Q
What happens in anaphase?
A
Sister chromatids are pulled apart and moved towards opposite poles
9
Q
What happens in telophase?
A
- Chromosomes return to threadlike forms
- New nuclear membrane forms
- Two nuclei form, one in each new cell
- Cytokinesis–division of cytoplasm
