Question

Choose the incorrect match w.rit. cell cycle.
O RNA synthesis - G1 phase
O DNA synthesis - S phase
O Centriole duplication - Go phase
o Organelle duplication - G2 phase​

Answer 1

Option (c) is incorrect

Explanation:

• Centriole duplication does not occur in Go phase . Centriole duplication occurs during S phase . Therefore option (c) is incorrect.
• G0 phase, is basically a resting phase , characterized by the disappearance of the cell cycle machinery and certain cyclin enzymes.
• Cells may remain in the Go phase until there is requirement for division. Some cells like epithelial cells never enter Go phase and are constantly dividing.
• Other pairs are matched correctly.
