One of the secondary structures exhibited by DNA is the famous Watson-Crick model. This model says that DNA exists as a double helix. The two strands of polynucleotides are antiparallel i.e., run in the opposite direction.

During G₁ phase the cell is metabolically active and continuously grow. S or synthesis phase marks the period during which DNA synthesis or replication takes place. In G₂ phase , proteins are synthesised. M phase represents the phase when the actual cell division or mitosis occurs.
