Each chromosome contains DNA in a double helix structure, which houses thousands of genes along the strand, each with their own loci. Centromere Functions One major function of a centromere is joining the sister chromatids. This category only includes cookies that ensures basic functionalities and security features of the website. For more than two decades, researchers have thought human chromosome 2 was produced as the result of the fusion of two mid-sized ape chromosomes and a … For the first time, Sutton and Bover suggested the role of chromosomes in heredity in 1902. Get in touch with us and we'll talk...Did you know that the smooth endoplasmic reticulum has a vital role in the detoxification process, that takes place in the liver? At the end of cell division, sister chromatids separate and become daughter chromosomes in the newly formed daughter cells.

There is hope though, with advances in genetic engineering for people with such conditions.The functions carried out by chromosomes form the very basis of life and its continuity. However, a parent with chromosomal abnormalities has higher chances of giving birth to a child with genetic disorders.

Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs and representing almost eight percent of the total DNA in human cells.. Chromosome 2 contains the HOXD homeobox gene cluster. Of these 23 pairs, 22 pairs, or 44 chromosomes, are non-sex chromosomes — also known as autosomes, and a single pair makes up a sex chromosome.Genes are located at a particular point on a chromosome, known as its locus.
