Environmental factors can have a big impact on DNA in several ways:
Mutagenesis: About 10% of changes in DNA happen because of things in our surroundings, like UV light from the sun and certain chemicals.
Epigenetics: Around 20% of how our genes work can be changed by what’s going on around us. This means our traits can be affected without actually changing the DNA itself.
DNA Repair: When there are environmental stresses, like pollution or toxins, our bodies need to fix DNA more often. This helps keep our genetic information stable and healthy.
These points show how closely DNA and the environment are connected.
