Answer to Problem 1TY

Option (b).

Explanation of Solution

Explanation for the correct answer:

Option (b) S phase. The S phase is the synthetic phase of the cell cycle. In this phase of the cell cycle, the amount of DNA and chromosomes are doubled by the process of DNA replication. Hence, it is the correct answer.

Explanation for the incorrect answer:

Option (a) G1 phase. The G1 phase of the cell cycle is responsible for the growth and promotion of the cell size. Hence, it is an incorrect answer.

Option (c) M phase. Mitosis is the process of the celldivision, which occurs in all the somatic cells present in the body of the multicellular organism. IN this stage, the replication does not take place. Hence, it is an incorrect answer.

Option (d) G2 phase. The G2 phase occurs after S phase, so, there is no need of DNA replication. Hence, it is an incorrect answer.

Option (e) none of the above. The replication of the DNA segment or the chromosomes occur in S phase. Hence, it is an incorrect answer.
