External factors can seriously affect how DNA is built and copied. Here are a few examples:
UV Radiation: This type of light can create problems in DNA, causing bits called thymine dimers. If these problems are not fixed, they can lead to changes in our genes, called mutations.
Chemicals: Some substances, like those found in tobacco, can stick to DNA and make it hard for it to be copied correctly.
Heat: Very high temperatures can cause DNA strands to break. This can mess up the stability of DNA and how accurately it gets copied.
All these points show just how much our surroundings affect the health of our genes!
