Open GB File

The GB file extension is specifically used for two applications, namely:

GenBank

In this case, the GB extension file is a sequence file format used to store DNA and protein sequences.

But what is GenBank?

GenBank is an open access sequence database or annotated collection of all publicly available nucleotide sequences and also contains their respective protein translations.

It is produced and maintained by the National Center for Biotechnology Information with International Nucleotide Sequence Database Collaboration.

The GB file serves as the data store for one or more sequences, and also contains metadata such as annotations, comments, and references.

The GB format is widely used by public databases and is considered by many to be the standard format for DNA and protein sequence files.

The GBK format is also used by DNA Sequence Databases, along with the GB format.

GameBoy

In this second case, the GB file is used as a read-only memory (ROM) file that contains the data of the Game Boy games, hence its acronym GB.

It was established as the first handheld computer in the Game Boy family, released in 1989.
