Answer: Mutation can affect an organism by resulting to a change in the number and structure of chromosomes (chromosomal mutation). A typical example of this type of mutation is Down's syndrome where the individual contains 47 instead of 46 chromosomes.
Mutation can also result to a change in the nucleotide sequence of the DNA molecule in a particular region of a chromosome(Gene mutation) an example of genetic mutation is sickle cell anemia

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.
During mitosis, the chromosome copies separate the nucleus divides and the cell divides. This produces identical two cells called daughter cells. The main purpose of mitosis is for growth and to replace worn out cells.
