Which of the phases of cell cycle is of longest duration ?

Text Solution

Verified by Experts

Interphase is to the longest duration. It has following events and is divided in the following phases
(a) `G_(1)` phase (Gap 1) Corresponds to the interval between mitosis and initiation of DNA replication. Cell is metabolically active and continuously grows but does not replicate its DNA.
(b) S-phase (Synthesis phase) Marks the peroid during which DNA synthesis or replication takes place.
(i) Amount of DNA per cell doubles.
(ii) No increase in chromosome number.
(c) `G_(2)` phase (Gap 2) Proteins are synthesised for the preparation of cell division, while cell growth continues.
