Cell Cycle Flashcards
1
Q
Sequences of cell cycle?
A
Interphase:
G1- intensive cellular synthesis
(S)yntheses- DNA replication
G2- further cellular synthesis
Mitosis- PMAT
Cytokinesis
2
Q
What happens during G1?
A
- synthesis of mRNA and proteins for DNA replication
- intensive cellular synthesis for form new organelles
- translation
- each chromosome = uncondensed form-> chromatin
3
Q
What happens during S phase?
A
- DNA replication
- histones are synthesised
- DNA content x2, each chromosome contains two identical DNA molecules in uncondensed form
4
Q
What happens during G2?
A
- cells continue cellular synthesis with mitochondria synthesis ATP to provide energy for nuclear division
- centrioles replicate-> 2 centrosomes; asters developed
