Definition
The process by which changes occur in the DNA sequence of an organism, including point mutations, insertions, and deletions, and how these changes affect the genetic code, protein synthesis, and ultimately, the phenotype of an organism
Summary
DNA mutations are essential changes in the genetic code that can influence an organism's traits and health. They can occur naturally or be induced by environmental factors. Understanding mutations helps us grasp how genetic diversity arises and how it can lead to evolution. Some mutations can cause diseases, while others may provide advantages, highlighting the complex role of mutations in biology. Studying DNA mutations also has practical applications in medicine and biotechnology. Genetic testing can identify harmful mutations, and gene therapy aims to correct them. By exploring the mechanisms and effects of mutations, we can better understand genetics and its implications for health and disease.
