Genome annotation is the process of identifying and labeling the function of genes and other regions of DNA within a genome. This involves identifying genes, coding sequences, regulatory sequences, and other functional elements within the genome. The goal of genome annotation is to provide a comprehensive understanding of the genetic makeup of an organism and how it functions. This information is invaluable for understanding biological processes, genetic variation, and disease mechanisms. Genome annotation is typically done using bioinformatics tools and databases, as well as experimental techniques such as RNA sequencing and protein analysis.
