हिन्दीA cell examined at G1 phase of the cell cycle contains 16 chromosomes and has a DNA content of 2C. What will be the number of chromosomes and the DNA content respectively in the same cell at G2 phase and after the completion of anaphase of mitosis?
View Answer & Solution
Correct answer · Option D
G2: 16 chromosomes, 4C; After anaphase: 32 chromosomes, 4C
Explanation
During S phase, DNA content doubles from 2C to 4C while chromosome number remains 16 (2n) in G2; at anaphase, sister chromatids separate into individual daughter chromosomes, temporarily doubling the chromosome count to 32 within the cell while DNA content remains 4C prior to cytokinesis.
