Question

Choose the incorrect pair of chromosome type and the position of centromere in the chromosome:

• A. Metacentric: Centromere at the centre of the chromosome
• B. Submetacentric: Centromere nearby the centre of the chromosome
• C. Acrocentric: Centromere near one end of the chromosome
• D. Telocentric: Centromere at one end of the chromosome

Answer 1

The correct option is C Acrocentric: Centromere near one end of the chromosome

Chromosome is an organized package of DNA found in the nucleus of the cell. Chromosome type is one of the characteristics used in cytotaxonomy. Based on the position of the centromere in the chromosome, it is divided into four types:
Metacentric: Centromere is present at the centre of the chromosome
Sub-metacentric: Centromere is present nearby the centre of the chromosome
Acrocentric: Centromere is distant from the centre but not at the end
Telocentric: Centromere is located at one end of the chromosome
