MESOMITOSIS Meaning and
Definition
-
Mesomitosis is a biological process that occurs during mitosis, specifically during the stage of cell division known as metaphase. It is characterized by the alignment and separation of paired homologous chromosomes, a phenomenon that occurs in certain organisms and serves to facilitate genetic recombination.
Unlike the more common process of mitosis, where chromosomes form pairs and align in a single plane, mesomitosis involves the pairing of two chromosomes, one at the top and the other at the bottom of a cell's nucleus. These chromosomes do not fully align along a metaphase plate but instead have some level of overlap, resulting in partial pairing or union. This partial alignment allows for the exchange of genetic material between the paired chromosomes through a process called crossing over.
The occurrence of mesomitosis is primarily observed in certain lower organisms, such as fungi and some algae. It is considered a deviation from the typical pattern of mitosis, and its function is not yet fully understood. However, it is hypothesized that mesomitosis plays a role in enhancing genetic variability, as crossing over during this process allows for the exchange and recombination of genetic material, leading to the generation of diverse offspring.
Overall, mesomitosis is a distinct type of cell division that involves partial chromosome pairing and genetic recombination during metaphase. Its significance lies in its potential to contribute to genetic diversity and its presence in specific organisms.
