The Cell Cycle A eukaryotic cell cannot divide into two‚ the two into four‚ etc. unless two processes alternate: doubling of its genome (DNA) in S phase (synthesis phase) of the cell cycle; halving of that genome during mitosis (M phase). The period between M and S is called G1; that between S and M is G2. So‚ the cell cycle consists of: G1 = growth and preparation of the chromosomes for replication; S = synthesis of DNA [see DNA Replication] and duplication of the centrosome; G2
