Detailed explanation-1: -The correct duplication and transmission of genetic material to daughter cells is the primary objective of the cell division cycle. DNA replication and chromosome segregation present both challenges and opportunities for DNA repair pathways that safeguard genetic information.

Detailed explanation-2: -The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

Detailed explanation-3: -The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells.

Detailed explanation-4: -The checkpoint kinases mediate arrest and allow repair. The checkpoint kinases promote the viability of cells following DNA damage through their ability to mediate cell-cycle arrest, which allows cells to repair DNA damage (Box 2).

Detailed explanation-5: -Cell division plays an important role in all living organisms, as it is essential for growth, repair and reproduction. This process helps in: Renewing of damaged cells.
