Question
Chapter 10.4, Problem 2SB
Summary Introduction
To review:
The action of cyclins – Cdks (cyclin-dependent kinases) in the transition of cycle regulation.
Introduction:
Cell division cycle is highly regulated and controlled in organisms. Several check-points present in each phase of the cycle ensure that the replication and division of the cell and the chromosomes are performed with fidelity and accuracy. Cyclins and Cdks are the regulators of the cell cycle.
