Though redundantly described as a resting phase, interphase does not really involve rest. Comment.

Explanation

1) In cell cycle, the stage at which the nucleus is not in a state of division is called interphase. It occurs between two successive divisions.
2) During interphase, cell prepares for division by undergoing growth as well as DNA replication in an orderly manner, though considered as resting phase.

3) On the basis of biochemical studies, interphase is subdivided. into 3 stages: `G_1` phase, Sphase and `G_2` phase.
`G_1` phase : Cellincreases in size. RNA and proteins are synthesised in large quậntity.
S-phase : DNA replication occurs and its content increases to 4c from 2c. `G_1` phase : Synthesis of proteins and RNA is continued. Various cell organelles are newly synthesised. The proteins and energy pools associated with the structure and movement of chromosomes are established.
