Accession numbers(登录号) are labels for sequences NCBI includes databases(such as Gen Bank that contain information on DNA, RNA, or protein sequences You may want to acquire information beginning with a query such as the name of a protein of interest, or the raw nucleotides comprising a dna sequence of interest DNA sequences and other molecular data are tagged with accession numbers that are used to identify a sequence or other record relevant to molecular data

What is an accession number? An accession number is label that used to identify a sequence. It is a string of letters and/or numbers that corresponds to a molecular sequence Examples(all for retinol-binding protein, RBP4 X02775 Gen Bank genomic DNA sequence NT030059 Genomic contig DNA Rs7079946 db sNP (single nucleotide polymorphism) N91759.1 An expressed sequence tag(1 of 170) RNA NM 006744 Refseq dNa sequence(from a transcript) NP007635 Refseg protein AAC02945 Gen Bank protein protein Q28369 Swiss Prot protein 1KT7 Protein data bank structure record
