Different types of Chromosomes
Chromosomes can be classified into four types based on the position of centromeres.
- Metacentric Chromosome: In these chromosomes, the centromere is in the middle. It gives V-shaped chromosomes.
- Sub-Metacentric Chromosome: The centromere is slightly off-center in these chromosomes. This gives rise to L-shaped chromosomes.
- Acrocentric Chromosome: The centromere is located towards one end, giving J-shaped chromosomes in acrocentric chromosomes.
- Telocentric Chromosomes: In this type of chromosome, the centromere is near the end or telomere of the chromosome. This gives chromosomes an I shape.
23 Chromosomes – Functions and Types of Chromosomes
Chromosomes are made of DNA molecules and are found in the nucleus of a cell. There are 23 chromosome pairs in humans. Transporting genetic information from one cell generation to the next is the main function of chromosomes. Several genes on each chromosome code for different proteins. The features of the entire organism are influenced by or determined by these genes.
