Question

Match the columns

	Column I		Column II
(a)	Metacentric	(i)	At the tip
(b)	Submetacentric	(ii)	Almost near the tip
(c)	Acrocentric	(iii)	At the middle
(d)	Telocentric	(iv)	Slightly away from middle

• A. a-i, b-iv, c-ii, d-iii
• B. a-ii, b-iv, c-i, d-iii
• C. a-iii, b-iv, c-ii, d-i
• D. a-iv, b-iii, c-i, d-ii

Answer 1

The correct option is C a-iii, b-iv, c-ii, d-i

i) Metacentric chromosomes are X-shaped chromosomes and the centromere are present in the centre so that the two arms are equal.

ii) Submetacentric chromosome is a chromosome in which the centromere is located near the slightly away from the centre and the two arms are slightly unequal in length and form L-shape.

iii) Acrocentric chromosome is a chromosome in which the centromere is located near to one end of the chromosome.

iv) Telocentric chromosome is a chromosome in which the centromere is located at the terminal end of the chromosome and their shape is similar to the letter i.

So, the correct answer is 'a-iii, b-iv, c-ii, d-i'.
