genetic information and toxic substances

How do toxic substances cause genetic mutations?

Toxic substances can cause genetic mutations through various mechanisms. They may induce direct DNA damage by forming adducts with DNA bases, leading to errors during replication. Some toxins generate reactive oxygen species, which can cause oxidative damage to DNA. Additionally, certain substances interfere with the normal function of DNA repair enzymes, exacerbating the accumulation of mutations. These mutations can lead to cancer and other genetic diseases.
