| 1 |
in what phase of mitosis does DNA replicate
|
interphase
|
|
| 2 |
interphase is divided into 3 phases. what are they ?
|
G1-presynthesis, S-DNA synthesis, G2- post DNA duplication
|
|
| 3 |
during what part of interphase is RNA and protein synthesis occurs
|
G1
|
|
| 4 |
what cells are either temporary or permanently in the G0 phase?
|
muscles and nerves
|
|
| 5 |
G1 phase is typically the checkpoint. in mammalian cells arrest of the G1 checkpoint is mediated...
|
p53
|
|
| 6 |
what causes cancer in humans
|
when the gene encoding for p53 is mutated it reduces the cell's ability to repair damaged DNa...
|
|
| 7 |
what occurs during the G2 pahse?
|
accumulation of energy for mitosis, sythesis of tubulin for mitotic microtubles, synthesis...
|
|
| 8 |
G2 phase is also the chekpoint for what action?
|
cell remains until DNA synthesized with defects is corrected
|
|
| 9 |
in what part of interphase there is maturing promoting factor MPF?
|
G2
|
|
| 10 |
what is the function of maturing promoting factor MPF?
|
induces beginning of mitosis, condensation of chromosomes, rupture of nuclear envelope
