Structure of chromosome: Chromosome breakage is the

Chromosome breakage is the physical breakage of subunits of a chromosome. It is usually followed by reunion (frequently at a foreign site, resulting in a chromosome unlike the original). Breakage and reunion of homologous chromosomes during meiosis are the basis for the classical model of crossing over, which results in unexpected types of offspring of a mating. Chromosomes are long strings of DNA wrapped around proteins to make them compact. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In this article we will discuss about the structure of chromosomes with the help of suitable diagram. Chromosome is present as individual bodies in the interphase as well as in the mitosis. The predominant component in the chromosome is DNA molecule. The genes are located in chromosome of the nucleus and can be called as the discrete unit of transmission of hereditary character, because it is the specific locus or spot on a chromosome carrying the genetic material or information for a ... This detailed explanation will cover the structure, types, function, replication, segregation, and chemical composition of chromosomes, providing a comprehensive understanding of their role in cellular processes and inheritance.
