Cell cycle II - Telophase
4 important questions on Cell cycle II - Telophase
Why is re-replication impossible?
When and how are replication origins licensed?
Licensing occurs via recruiting the MCM helicase complex to ORC via cdc6 and Cdt1 ( only possible when cdc6 and Cdt1 are not phosphorylated)
When and how are replication origins fired?
When an origin fires cdc6 and Cdt1 are phosphorylated by CDKs, they leave the origin resulting in not being able to target MCM helicases
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Which 4 steps occur as long as replication forks are active?
2. Chk1 phosphorylates other proteins like the anaphase inhibitor Pds1 and Cdc25 phosphatase
3. This inhibits mitosis-specific pathways
4. The cell is maintained in S/G2
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
