Question

A chromosome which has centromere near the end is called

• A. Metacentric
• B. Sub-metacentric
• C. Acrocentric
• D. Telocentric

Answer 1

The correct option is C

Acrocentric

The correct option is C:

Explanation of the correct option

1. A chromosome with the centromere near the end of the chromosome rather than in the middle.
2. Humans have five pairs of acrocentric autosomes on average (chromosomes 13, 14, 15, 21, 22).
3. The Y chromosome is acrocentric as well.

Explanation of the incorrect options

Option A:

A metacentric is a chromosome bearing a centromere in the middle, which divides the chromosome into two arms of roughly equal length.
Option B:

Sub-metacentric is a chromosome with a centromere that is positioned sub-median, resulting in chromosomal arms that are somewhat uneven in length.

Option D:

A telocentric chromosome is one in which the centromere is located at the end of the chromosome and there is just one chromosomal arm.

A chromosome that has a centromere near the end is called acrocentric.
