Web19 jan. 2024 · In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that … WebCorrect option is D) DNA is replicated during the S phase of a cell cycle. So, during the metaphase stage, each chromosome (i.e., each chromatid pair) will contain two molecules of double-stranded DNA (one molecule per sister chromatid) in mitosis. So, the correct option is 'two'. Solve any question of Cell Cycle And Cell Division with:-
