Question

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

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

Answer 1

Answer: (D)

Acrocentric

Chromosomes are classified according to the position of the centromere. If the centromere is present somewhere in between, but not exactly in the middle, of the chromosome, it is called as sub metacentric chromosomes. Chromosomes having centromere exactly in the middle are called as metacentric. Acrocentric chromosomes have centromere located very near to its end. They appear as rod-shaped or “i “ shaped chromosomes. The telocentric chromosomes have centromere located at the end of the chromosome. Thus, the correct answer is option D.
