How is cell reproduction controlled?

Regarding this, what controls reproduction of the cell?
During mitosis, the nucleus, which holds the cell's genetic information, is divided. During cytokinesis, the rest of the cell is divided. The result is two newly formed, identical cells. These two phases are important for the control of cell division.
Furthermore, why do cells stop reproducing? Cells – except for cancerous ones – cannot reproduce forever. When aging cells stop dividing, they become “senescent.” Scientists believe one factor that causes senescence is the length of a cell's telomeres, or protective caps on the end of chromosomes. Every time chromosomes reproduce, telomeres get shorter.
Similarly, how do cells replicate?
Cells Can Replicate Their DNA Precisely. Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.
What is the purpose of cell reproduction?
Cell division has three main functions which are reproduction of unicellular organisms and the production of gametes and growth in eukaryotes. The process of meiosis in eukaryotes produces sex cells or gametes with half the chromosome compliment of somatic cells.
