The chromosomes in which the centromere is situated close to one end are:
Correct answer: D. Acrocentric
- A. Telocentric
- B. Sub-metacentric
- C. Metacentric
- D. Acrocentric
Explanation
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 a sub-metacentric chromosome. Chromosomes having centromere exactly in the middle are called metacentric. Acrocentric chromosomes have a centromere located very near their end. They appear as rod-shaped or "i" shaped chromosomes. The telocentric chromosomes have a centromere located at the end of the chromosome.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
