==Data formats==
Human gene naming is provided by the HUGO Gene Nomenclature Committee: https://www.genenames.org/
DNA data repositories
* NCBI: National Center for Biotechnology Information
* EMBL: European Molecular Biology Laboratory
* DDBJ: DNA Data Bank of Japan
DNA sequence data formats
* GenBank: human readable, can be processed by computer (fixed width, first 10 characters are an identifier).
** NCBI Reference Sequence (RefSeq) project provides sequence records and related information.
** Prefix AC_ in acession number is for genomic data, NM_ is for mRNA.
* FASTA: Sequence information
** Header starts with > and is followed by a sequence ID.
** Sequence lines should wrap always at the same width.
** Lower-case letters may indicate repetitive regions.
* FASTQ: Current standard for sequencing data
** It is essentially FASTA with quality values for the sequence.
** Quality is on a scale from 0 - 40 and represented by a distinct character.
** Upper case letters ABCDEFGHI means high quality.
** Special letters !"#$%&'()*+,-. mean low quality.
