Question:

The chromosomes in which centromere is situated close to one end are

Options:

1. metacentric
2. acrocentric
3. telocentric
4. sub-metacentric

Solution:

Acrocentric chromosome has centromere, which is situated almost close to one end. There are 4 types of chromosomes according to location of centromere on chromosome (chromatid arms) as (i) Metacentric X-shaped chromosomes with centromere exactly at the middle of two arms. Chromosomes 1 and 3 are metacentric. (ii) Acrocentric When one arm is short and centromere is inner to telomere. It is hard to observe short arm but still it is present. Chromosome 13, 14, 15, 21 and 22 are acrocentric. (iii) Submetacentric Centromere is sub median, so Arm's length are unequal but observable. Chromosomes 4 and 12 are submetacentric. (iv) Telocentric When centromere is located at the terminal end of the chromatid arm. Humans do not possess telocentric chromosome.
