Question

A chromosome consists of two similar strands called one, attached to each other at a point known as

• A. 1 - Chromatids, 2 - Centromere
• B. 1 - Chromatin, 2 - Centromere
• C. 1 - DNA, 2 - Chromatin
• D. 1 - Chromatin, 2 - Nucleosome

Answer 1

The correct option is A 1 - Chromatids, 2 - Centromere

Chromatids are the one-half of two identical threadlike strands of a replicated chromosome and the two similar threads or chromatids attached to each other by a narrow non-stainable or very lightly stained area called as the centromere.

So, the correct answer is option A.
