Can you elaborate on the significance of cell division in relation to the development and healing process of living organisms?
Cell division also plays a key role in the maintenance of genomic stability. In the process of cell division, DNA replication must occur accurately in order to ensure that each daughter cell receives an identical copy of genetic information. Any errors or mutations that occur during DNA replication can have serious consequences, such as cancer development. Therefore, the proper regulation of cell division is essential to ensure the accuracy of DNA replication and to prevent the formation of genetic mutations. Additionally, telomeres, which are the protective caps at the end of chromosomes, shorten each time a cell divides and eventually become too short to protect the chromosomes leading to cell senescence or apoptosis, which limits the number of cell divisions, and therefore the life of a tissue or organ. This is an important mechanism in the aging process and in preventing cancer.
