Gene Annotation is the process of identifying and labeling the functional elements of a genome. This includes determining the locations of genes, their sequences, and the roles they play in biological processes. By analyzing DNA sequences, researchers can predict which regions are likely to code for proteins or have regulatory functions. Accurate gene annotation is crucial for understanding the biology of an organism and can aid in fields like genomics, medicine, and evolutionary biology. It helps scientists interpret genetic information, leading to discoveries about how genes influence traits and diseases.
