If the cell at G1 phase at 2 Giga base pairs of DNA, what is the DNA content of the cell right before Telophase II?

(a) 1 Giga base pairs

(b) 2 Giga base pairs

(c) 3 Giga base pairs

(d) 4 Giga base pairs

I got this question in my homework.

The question is from Chromosomal Theory of Inheritance-2 in chapter Principles of Inheritance and Variation of Biology – Class 12

Best answer
Right answer is (b) 2 Giga base pairs

To explain: Cell at G1 phase has a pair of chromosomes. By the end of Anaphase II, it still has a pair of chromosomes. Hence the DNA content would be almost the same as at the time of G1.
