The Deep Dive
Mutations are changes in the DNA sequence of an organism’s genome. These alterations can occur naturally during DNA replication or be induced by environmental factors like radiation or chemicals. While some mutations are harmless or even beneficial, others can lead to genetic disorders or cancer. Think of mutations like typos in a book—sometimes they change the meaning entirely!
Carcinogens are substances or exposures that are capable of causing cancer in living tissue. They can be found in everything from tobacco smoke and asbestos to certain chemicals in processed foods. Carcinogens work by damaging the genetic material in cells, which can lead to the uncontrolled growth characteristic of cancer. So, while some things may be delicious or fun, it’s always good to know what’s lurking in the shadows!
