cell cycle Flashcards
1
Q
interphase
A
DNA replication and normal cell activities
2
Q
interphases phases
A
G1-normal cell activites
S-DNA replication
G2-prepare for divison
M-mitosis
3
Q
Mitosis phases in order
A
Prophase
Metaphase
Anaphase
Telephase
4
Q
Prophase
A
chromatin condense and form chromosomes, centrioles move toward poles, nuclear envelope begins to disinegrates
5
Q
metaphase
A
chromosomes move towards middle equator
6
Q
anaphase
A
chromatin pulled apart by spindle fibers, form two identical chromosome, cytokinesis begins with cleave furrow
7
Q
telephase
A
chromosome begin to unwind, nuclear envelope reforms, cytokinesis continues
8
Q
mitotic DNA process
A
- DNA as chromatin
- DNA seperates and duplicates
- Chromatin condense and become chromatid
- two chromatid held together by centromere form chromsome
