Structure of Chromosome
Each chromosome is made up of three fundamental parts:
- Chromatids: Each chromosome is made up of two sister chromatids.
- Centromere: Two sister chromatids are joined at a point called the centromere.
- Telomere: The ends of each chromosome are called the telomere.
- The entire set of chromosome of an organism that has been organised according to shape, size, and number is called the karyotype.
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.
