Cdk Control of DNA Replication Timing

Cdk control of DNA replication timing helps cells copy DNA once each cycle. The cell cycle has four main stages: G1, S, G2, and M. In G1, the cell grows. In S phase, it copies its DNA. In G2, it prepares to divide. In M phase, mitosis divides the cell content into two daughter cells.

In eukaryote...

In eukaryotes, DNA replication takes place during the S-phase of the cell cycle. The cell cycle control system, consisting of a network of regulatory proteins, governs the progression of the cell cycle.

The S-phase cyclin-dependent kinase, or S-Cdks, are enzyme complexes involved in cell cycle control during S-phase. This control system e...
