NEET 2004 Biology question

In the somatic cell cycle :-

(1)DNA replication takes place in S-phaseCorrect
(2)A short interphase is followed by a long mitotic phase
(3)G2 phase follows mitotic phase
(4)In G1 phase DNA content is double the amount of DNA present in the original cell

Answer: (1)

Solution

The somatic cell cycle consists of interphase (G1, S and G2) followed by the M (mitotic) phase. DNA is replicated only during the S (synthesis) phase, so the DNA content doubles from 2C to 4C in S phase. Interphase is the longer part of the cycle (in human cells about 95%
