Question

Match the column: Column I Column II A. Metacentric chromosomal 1\. Middle centromere B. Sub-metacentric 2\. Centromere slightly way from middle C. Acrocentric 3\. Centromere close to its end D. Telocentric 4\. Terminal centromere (a) \(\mathrm{A}-1, \mathrm{~B}-2, \mathrm{C}-3, \mathrm{D}-4\) (b) \(\mathrm{A}-2, \mathrm{~B}-1, \mathrm{C}-3, \mathrm{D}-4\) (c) A-1, B-2, C-4, D-3 (d) \(\mathrm{A}-4, \mathrm{~B}-3, \mathrm{C}-2, \mathrm{D}-1\)

Short answer

\(\mathrm{A}-1, \mathrm{~B}-2, \mathrm{C}-3, \mathrm{D}-4\).

Step-by-step solution

Understanding the Terms

First, it is important to know what each term means. Metacentric chromosome refers to a chromosome where the centromere is in the middle, Sub-metacentric is when the centromere is slightly away from the middle, Acrocentric refers to a chromosome in which the centromere is close to its end and Telocentric refers to a chromosome where the centromere is at the terminal or end position.

Matching the Terms with their Definitions

Now, match the terms from Column 1 with the definitions in Column II. Metacentric chromosome matches with 'Middle centromere', corresponding to 1 in Column II. Sub-metacentric matches with 'Centromere slightly way from middle', corresponding to 2 in Column II. Acrocentric corresponds to 'Centromere close to its end', which is 3 in Column II, and Teleocentric matches with 'Terminal centromere', which is 4 in Column II.
