Mitochondria and their 16.5-kb circular genomes (mtDNA) undergo constant turnover in arrested primary oocytes for decades in humans (1, 2).Frequent DNA replication and lack of efficient DNA repair mechanism in the mitochondrion contribute to a mutation rate that is ∼10-fold higher than that of the … Web1 mrt. 2024 · The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed ...
