In mitosis, chromosomes are important. What are two things that happen to chromosomes during mitosis? The Role of Chromosomes in Mitosis

Mitosis and the Role of Chromosomes

The essential component of mitosis is the function of chromosomes. This type of cell division produces identical genetically-identical daughter cells out of a single parent. The chromosomes have a crucial role during mitosis. They ensure that the genetic material reproduces properly and gets distributed correctly to the daughters cells. The chromosomes are affected by two things during this process. Condensation is the first. This occurs when the chromosomes are made more compact and visible by the cells as they prepare to divide. The chromatin fibers are the strands made up of DNA and proteins that form the chromosomes. They become shorter and more dense as a result. Condensation of these fibers makes them more easily discernible, and facilitates segregation when the chromosomes are separated (Krishnan, Dhanasekaran, et. al. 2020; Dhanasekaran, et. al. 2017,). Segregation is the second event that occurs to the chromosomes. This is when the chromosomes are separated into separate sets of sister-chromatids. This is when each of the chromosome’s chromatids aligns in the centre of the cell, facing each other. When the two chromosomes are properly aligned the kinetochore proteins attach to the centromere to generate tension which allows sister chromatids in the cell to be pulled apart (Bozhkov, Beaud, and Alvarez, 2019).
