简介：
Overview
This study investigates the regulatory mechanisms of the cell cycle in Eukaryotes, with a focus on the roles of cyclin-dependent kinases (CDKs) in initiating DNA replication and maintaining stable germline. The yeast two-hybrid assay is employed to efficiently isolate interaction-null or impaired mutants, facilitating a better understanding of protein interactions critical for cell cycle regulation.
