Cell Division


When a cell divides it must go through a process called mitosis. Mitosis is a process that describes the various steps that occur in a cell before and after initial division
The cell cycle as its most commonly called consist of the
  • G1- cell growth begins
  • S- Protein synthesis and chromosomal replication occurs
  • G2- cell now has duplicate copies of chromosomes
  • M Phase- centrioles lock onto each end of the chromosomes and then pull them apart to make two cells

Terms (chromosome - super coiled DNA wounded together with histones)
All of the above is moderated by two molecules called "CDK-Cyclin"
