Question

Match List - I with List - II. Choose the correct answer from the options given below:

	List - I		List - II
(a)	Metacentric chromosome	(i)	Centromere situated close to the end forming one extremely short and one long arms.
(b)	Acrocentric chromosome	(ii)	Centromeres at the terminal end
(c)	Sub-metacentric	(iii)	Centromere in the middle forming two equal arms of chromosomes
(d)	Telocentric chromosome	(iv)	Centromere slightly away from the middle forming one shorter arm and one longer arm

• A. (a)- (iii); (b) - (i); (c) - (iv);(d) - (ii)
• B. (a)- (i); (b) - (iii); (c) - (ii);(d) - (iv)
• C. (a)- (ii); (b) - (iii); (c) - (iv);(d) - (i)
• D. (a)- (i); (b) - (ii); (c) - (iii);(d) - (iv)

Answer 1

The Correct Option is A

To match the chromosomes in List - I with their descriptions in List - II, we need to understand the definition of each type:

1. Metacentric chromosome: The centromere is located in the middle, forming two equal arms (iii).
2. Acrocentric chromosome: The centromere is situated close to the end, forming one extremely short arm and one long arm (i).
3. Sub-metacentric: The centromere is slightly away from the middle, forming one shorter arm and one longer arm (iv).
4. Telocentric chromosome: The centromere is at the terminal end (ii).

Therefore, the correct matching is:

• (a) Metacentric chromosome - (iii)
• (b) Acrocentric chromosome - (i)
• (c) Sub-metacentric - (iv)
• (d) Telocentric chromosome - (ii)

The correct option is:

(a)- (iii); (b) - (i); (c) - (iv);(d) - (ii)
