Cell Cycle

Cell division occurs in two main stages:-

• Nuclear Division:
  • the process which the nucleus divides:
    • Mitosis
    • Meiosis.
• Cell Division:
  • follows nuclear division - process which the whole cell divides.

Before dividing of nucleus, DNA has to be replicated - ensures all daughter cells have genetic info - to produce enzymes & other proteins.

DNA replication process is very precise, because all new cells almost identical to original.
