Conservation, the act of protecting Earth's natural resources for current and future generations
Answer:
CDK is inactive without a cyclin bound to it.
Explanation:
CDKs are the cyclin-dependent kinases. These protein kinases serve to regulate the various stages of the cell cycle. Cyclins are the regulatory proteins. The levels of cyclins fluctuate during the cell cycle. Cyclins bind to respective CDKS to activate them. Unless cyclins bind to CDKs, these protein kinases are inactive. Cdk associates with cyclin and forms a cyclin–Cdk complex. For example, mitosis specific Cdk bind to cyclins and activated M-Cdk then activates the proteins that facilitate mitosis and inactivate the one that inhibits mitosis.

Answer:
Explanation:
Ccrm is a DNA methyl transferase. This enzyme helps in switching from fully methylated stated to hemimethylated state at its target motif. In this way this gene helps in expression of genes which helps in controlling the cell cycle progression.
When the Ccrm gene is found to be non functional in form. Then there is no switching occur from fully methylated to hemi methylated state at its target motifs. That's why there is not found expression of those genes which are involved in the cell cycle progression. In this way there is not found replication of DNA and there is not found replication of chromosome. That's why there is found single chromatid containing chromosome even after S phase. That's why the daughter cell will not get equal amount of genetic material. And cell cycle becomes futile.
