Which cell cycle phase are most cells in our body in?
G2
S
M
G0
During which mitotic phase does the breakdown of the nuclear envelope occur?
Prophase
Metaphase
Anaphase
Telophase
Cyclins and CDKs control progression through the cell cycle checkpoints by inhibiting transitions from one phase to the next (negative control).
True
False
At G2/M checkpoint, Cdks target nuclear proteins: - Phosphorylation of ❌ leads to chromatin condensation. - Phosphorylation of ❌ leads to the disassembly of the nuclear lamina. - Phosphorylation of ❌ leads to the disassembly of the NPC.
Exportin moves back to the nucleus via the [Ran GDP] gradient.
In the , converts RanGDP to RanGTP.
