Accession number

Meaning in genetics & biotechnology, with examples

nounAdvanced term

In genetics & biotechnology, accession number means: A unique code given to a sequence or dataset when it is stored in a public database such as GenBank, so that others can find exactly the same record.

In Turkish: erişim numarası, kayıt numarası

How it is used

Used in papers, data sharing and clinical reports. Journals ask authors to deposit sequencing data and give the accession numbers in the paper. RefSeq accessions starting with NM_ identify the transcript in variant names. The version comes after a dot, as in NM_000546.6.

Example sentences

  1. The raw reads are available in the SRA, and the accession number is given in the data availability statement.

  2. Always give the transcript accession number when you report a variant.

Common collocations

  • GenBank accession number
  • deposit data
  • under accession number
  • transcript accession
  • accession version
  • BLASTBasic Local Alignment Search Tool: a widely used program that compares a DNA or protein sequence with large databases to find similar sequences.
  • annotationAdding biological information to sequence data, for example marking where the genes are in a genome, or giving each variant its predicted effect and population frequency.
  • reference genomeA standard, high-quality genome sequence for a species that researchers use as a common map when aligning reads and describing variants.
  • bioinformaticsThe use of computers, statistics and software to store, analyze and interpret biological data, especially DNA, RNA and protein sequences.
