Chromosomal integrity refers to the stability and proper structure of chromosomes, which are the thread-like structures in cells that carry genetic information. Maintaining chromosomal integrity is crucial for accurate cell division and the prevention of genetic disorders. Any damage or abnormalities in chromosomes can lead to issues such as cancer or inherited diseases. Several mechanisms help ensure chromosomal integrity, including DNA repair systems and checkpoints during the cell cycle. These processes detect and fix errors, preventing the transmission of damaged genetic material to daughter cells. Proper functioning of these mechanisms is essential for overall cellular health and organismal development.
