Questão 3
Questão
Cyclins and CDKs control progression through the cell cycle checkpoints by inhibiting transitions from one phase to the next (negative control).
Responda
True
False
Questão 4
Questão
At G2/M checkpoint, Cdks target nuclear proteins:
- Phosphorylation of [blank_start]histones and condensins[blank_end] leads to chromatin condensation.
- Phosphorylation of [blank_start]lamins[blank_end] leads to the disassembly of the nuclear lamina.
- Phosphorylation of [blank_start]nups[blank_end] leads to the disassembly of the NPC.
Responda
histones and condensins
lamins
nups
