An anaphase chromosome contains [DPMT 1991]
A) 1 DNA molecule

B) 3 DNA molecule

C) 2 DNA molecule

D) 4 DNA molecule.explain in detail..

Dear student,
The correct answer is D. An anaphase chromosome of meiosis consists of a tetrad which means four chromatids and thus 4 DNA molecules.This is because the sister chromatids are pulled apart and move towards opposite poles of the cell. Thus, each chromatid contains DNA, therefore, 4 chromatids of a chromosome contains 4 DNA.

Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the equator of the cell on the equatorial plane. The sister chromatids are pairs of identical copies of DNA joined at a point called the centromere.
