Chromosomal instability is a term used to describe a condition in which cells have an abnormal number or structure of chromosomes. This can result in genetic abnormalities, cell division errors, and ultimately contribute to the development of various diseases, including cancer. Researchers study chromosomal instability to better understand how it occurs, its impact on cellular function, and potential ways to prevent or treat diseases associated with this genetic instability. By identifying the causes and consequences of chromosomal instability, scientists aim to develop new therapeutic strategies and diagnostic tools for a range of conditions linked to abnormal chromosome structure and number.
