Answer the following by using the term which is used for describing a chromosome having a centromere at its middle.

There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric.


Chromosomes are found within most living cells’ nucleus and consist of DNA tightly bound into thread-like structures. Chromosomes are divided into two parts, with a constriction point in the middle known as the centromere. The position of the centromere classifies the four types of chromosomes in animal cells.

  • The centromere is present right in the middle of the chromosome, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric.
  • Submetacentric chromosomes have the centromere slightly offset from the centre, leading to a slight asymmetry in the length of the two sections.
  • Acrocentric chromosomes have a centromere that is severely offset from the centre leading to one very long and concise section.
  • Telocentric chromosomes have the centromere at the very end of the chromosome.
