Match column-I with column-II and choose the correct option.
Column-IColumn-II
(Chromosome)(Position of Centromere)
A. MetacentricI. At the tip
B. SubmetacentricII. Almost near the tip
C. AcrocentricIII. At the middle
D. TelocentricIV. Slightly away from the middle

A. A III; B IV; C II; D I

B. A IV; B III; C II; D I

C. A I; B II; C III; D IV

D. A IV; B III; C I ; D II

Correct Answer : A.


Metacentric chromosomes have the centromere in the centre, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric. Sub metacentric chromosomes are a chromosome with the centromere so placed that it divides the chromosome into two arms of strikingly unequal length. Acrocentric chromosomes have a centromere which is located almost near the tip leading to one very long and one very short section. Human chromosomes 13, 15, 21, and 22 are acrocentric. Telocentric chromosomes have centromere which is located at the terminal end. Telomeres may extend from both ends of the chromosome. Humans do not possess telocentric chromosomes.
