Mutagens

Mutagens are agents that can cause changes or mutations in the DNA of an organism. These changes can alter genes, potentially leading to health issues like cancer or genetic disorders. Mutagens include certain chemicals, radiation (like UV rays or X-rays), and even some viruses. Not all mutations are harmful; some may have no effect or even be beneficial. Understanding mutagens is important because they help us identify factors that can cause genetic damage and develop strategies to reduce exposure, promoting better health and safety.
