Question

Each chromosome at the end of anaphase stage of a bone marrow cell in our body has ______.

• A. Two chromatids
• B. No chromatids
• C. Only one chromatid
• D. Several chromatids

Answer 1

The correct option is C Only one chromatid

The bone marrow cells are somatic cells and undergo mitotic division or equational division. During the Anaphase of mitotic division sister chromatids of every chromosome separate and enter into distinct cells after cytokinesis. Therefore, during the beginning of anaphase the chromosome has two chromatids at the end of anaphase each chromosome consists of a single chromatid.

So, the correct answer is 'Only one chromatid'
