DNA damage is a term used to describe the various types of injuries that can occur to an organism's genetic material. There are several synonyms for this term, including DNA injury, genetic damage, genomic instability, and DNA strand breaks. Each of these terms refers to different aspects of DNA damage and can be used interchangeably in scientific research. DNA damage can occur naturally due to exposure to radiation, chemical toxins, or can be caused by mistakes during DNA replication. However, it can also be repaired through various mechanisms including cellular repair systems. DNA damage is a critical area of research for scientists as it has been linked to several diseases and cancer development.
