Question

An anaphase chromosome contains

• A. 1 DNA molecule
• B. 3 DNA molecule
• C. 2 DNA molecule
• D. 4 DNA molecule

Answer 1

The correct option is A 1 DNA molecule

During mitosis, anaphase stage is characterized by splitting of the centromere. The DNA molecule in each chromosome replicates in the synthesis or S phase of interphase and thus, it possess two DNA molecules. At anaphase stage, each chromosome splits at the centromere and each daughter chromosome thus produced is left with a single molecule of DNA only.

So, the correct answer is option A.
