4、f the bioinformaticsDatabase and web serverPart II Introduction to bioinformatics webservices created in Su Zhens labPart III Construction of database and web services,14,Three major public DNA databases,In 1988, 由此三家组成了国际核酸序列数据库协作组织（INSDC），规定：1、数据交换与共享（每24小时进行一次）2、使用统一的数据记录格式处理提交数据，以保证各数据库相应记录在内容上的

5、一致性。3、数据的维护与更新。Each database updates only the records that were directly submitted to it.,19,Accession number 是用来确定一个记录的标签。Examples (all for retinol-binding protein, RBP4):X02775GenBank genomic DNA sequence（1+5，2+6）NT_030059Genomic contig in RefSeqRs7079946dbSNP (single nucleotide polymorphism)N9175
