Annotation is the process of determining the location and function of genes and functional (e.g., regulatory) sequences within a genome sequence.
Annotating is beneficial for a variety of reasons, depending on the type of text being read. Annotating a text for academic or professional purposes allows you to return to specific points for review. This could be because a specific passage section is unclear and needs to be clarified, or it could be because that section provides a starting point for analysis or research. It is much easier to return to a specific part of a text by keeping track of one's thoughts and questions while reading rather than attempting to remember a thought or question after the entire text has been read through.
