Question

Identify the structures indicated by labels (i), (ii), (iii) and (iv) select the correct option.

• A. (i) - Chromatid, (ii) - Centriole, (iii) - Centromere, (iv) - Chromoseome
• B. (i) - Chromoseome, (ii) - Centriole, (iii) - Centromere, (iv) - Chromatid
• C. (i) - Chromatid, (ii) - Centromere, (iii) - Centriole, (iv) - Chromoseome
• D. (i) - Chromoseome, (ii) - Centromere, (iii) - Centriole , (iv) - Chromatid

Answer 1

The correct option is A (i) - Chromatid, (ii) - Centriole, (iii) - Centromere, (iv) - Chromoseome

The given structure can be found during the metaphase stage as all the chromosomes arrange themselves on the equatorial plate. The chromosome contains two coiled structures thought its length which is known as the chromonemata. A chromatid is a half chromosome or daughter chromosome. The chromatids are connected at the centromere or primary constrictions.

So, the correct option is '(i) - Chromatid, (ii) - Centriole, (iii) - Centromere, (iv) - Chromoseome'
