The key difference between metacentric and telocentric chromosomes is that in metacentric chromosomes, the centromere is located in the middle of the chromosome while in telocentric chromosomes, the centromere is located at the end of the chromosome.
A chromosome is a thread-like structure made from DNA and histone proteins. They contain genetic information of an organism. There are several distinct regions of a chromosome, including chromatids, centromere, chromomere and telomere. The centromere is the visible point of constriction in the chromosome which joints sister chromatids together. It is important during cell division. Depending on the position of the centromere in a particular chromosome, there are six different types of chromosomes: acrocentric, sub-metacentric, metacentric, telocentric, dicentric and acentric.
