On this page, we mainly focus on the genetic aspects of the cell cycle - meaning the replication of DNA and the division of the nucleus. The cellular aspects of cell division ar looked into on the page "Cell Cycle". The button on the right is a convenient way to switch to that page.
Cell division is a crucial process to replace old cells and to allow organisms to grow (mitosis) or to create gametes for reproduction (meiosis). However, before cells can be divided, their DNA needs to be copied in order to ensure that both daughter cells receive all the genetic information that is necessary for their survival. The process responsible for copying the DNA is called (identical) replication of DNA. It takes place during interphase.
This video explains how the replication of DNA works.
