Hypothesis
How do CDKs promote DNA replication in eukaryotes?
Conclusion
CDK-dependent phosphorylations of Sld2 and Sld3 are minimal requirements for the initiation of DNA replication.
Supporting Evidence
- Phosphorylation of Sld2 and Sld3 is essential for CDK-dependent activation of DNA replication.
- Bypassing CDK activity can still allow DNA replication under certain conditions.
- The interactions between phosphorylated Sld2, Sld3, and Dpb11 are crucial for initiating DNA replication.
Takeaway
CDKs help start the process of copying DNA in cells by adding special tags to certain proteins.
