Final answer:
Oxidative stress is associated with chromosomal damage and is caused by the release of reactive molecules that stick to other pieces of DNA. This damage can be caused by physical stress or environmental factors.
Step-by-step explanation:
Oxidative stress is associated with chromosomal damage and is caused by the release of reactive molecules that stick to other pieces of DNA. This damage can be caused by physical stress or environmental factors. Oxidative stress occurs when reactive oxygen species (ROS) remove electrons from other molecules, leading to oxidization and reactivity. This can result in permanent damage to cellular components, including DNA. Damaged DNA can lead to genetic mutations and increase the risk of diseases like cancer.
