Structure of Chromosomes (With Diagram) | Cell Nucleus | Biology

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 [...]

Interchanges Involving Pairs of Chromosomes

In this article we will discuss about the interchanges involving more than two pairs of chromosomes. When 3 or more pairs of non-homologous chromosomes are involved in translocation, it is called a complex translocation, complex interchange or multiple translocation. In a single cell, two or more independent heterozygous interchanges show two or more quadruples at MI. Such interchanges are obtained [...]
