Mutations are changes in the genetic material of an organism that can be inherited by the next generation. They can occur spontaneously, as a result of errors during DNA replication, or can be induced by environmental factors such as radiation or chemical exposure. Mutations can have a range of effects on an organism, from being neutral and having no impact on the individual to causing genetic disorders or diseases. Researchers study mutations to understand how they contribute to evolution, disease, and genetic diversity, and to develop strategies for preventing or treating genetic disorders. This research area is critical for understanding the genetic basis of diseases and for advancing medical treatments and genetic engineering technologies.
