A) telomere
B) centromere
C) chromomere
D) centrosome
Correct Answer: B
Solution :
Shape of chromosome is determined by centromere. The position of centromere is constant for a particular chromosome on the basis of its position, the chromosomes are categorised as [a] Metacentric-The V-shaped chromosome, in which centromere lies in the middle of chromosome so that the two arms are almost equal. [b] Submetacentric-These are J or L shaped chromosomes with centromere slightly away from the mid-point so that the two arms are unequal. [c] Acrocentric-rod shaped chromosomes having subterminal centromere. One arm is very long and the other is very small. [d] Telocentric-rod-shaped with centromere occupying a terminal position. One arm is very long and the other is absent.
