What are genetic mutations and how do they occur?

Genetic mutations are alterations in the DNA sequence that can lead to changes in an organism's traits. They occur through various mechanisms such as errors during DNA replication, exposure to mutagenic agents like radiation or chemicals, or spontaneous changes in DNA over time. Mutations can be beneficial, harmful, or have no noticeable effect, influencing genetic diversity and potentially contributing to evolution and disease development. For more information, visit SCUHS.
