Question

Which of the following type of chromosomes has only one telomere?

Options

• Telocentric

• Sub metacentric

• Metacentric

• Acrocentric

Answer 1

Telocentric

Explanation:

On the basis of morphology, chromosomes are classified into four types. Metacentric with centromere in centre and two equal arms. Sub metacentric with centromere slightly shifted from centre to have one arm long and one short. Acrocentric with centromere shifted to one end and one arm is very long and the other is very short. Telocentric with centromere at one end so only one arm and one telomere.
