How do I find my NCBI revision history?
To see the revision history of a sequence, append report=girevhist to the record’s URL. For example, accession U46667’s revision history’s URL is http://www.ncbi.nlm.nih.gov/nuccore/U46667?report=girevhist.
How do I search for a GenBank sequence?
How to: Find transcript sequences for a gene
- Search the Gene database with the gene name, symbol.
- Click on the desired gene.
- Click on Reference Sequences in the Table of Contents at the upper right of the gene record.
How sequences are retrieved from GenBank?
There are several ways to search and retrieve data from GenBank. Search GenBank for sequence identifiers and annotations with Entrez Nucleotide. Search and align GenBank sequences to a query sequence using BLAST (Basic Local Alignment Search Tool). See BLAST info for more information about the numerous BLAST databases.
Is GenBank and NCBI the same?
GenBank is built and distributed by the National Center for Biotechnology Information (NCBI), a division of the National Library of Medicine, located on the campus of the U.S. National Institutes of Health (NIH) in Bethesda, MD, USA.
How do I view my PubMed history?
The History page displays all of your searches that have been run recently in PubMed. Each search is given a search statement number that can be used to build and refine searches. To use this feature, first perform a search in the PubMed search box, then click on the History Tab (see animation in Figure 1).
How do I access GenBank?
Complete bimonthly releases and daily updates of the GenBank database are available by FTP. To access GenBank and its related retrieval and analysis services, begin at the NCBI Homepage: www.ncbi.nlm.nih.gov.
How do I read my blast results?
How to Interpret BLAST Results
- Maximum Score is the highest alignment score (bit-score) between the query sequence and the database segments.
- Total Score is the sum of the alignment scores of all sequences from the same db.
- Percent Query Coverage is the percent of the query length that is included in the aligned segments.

How many sequence records are now stored in GenBank?
Currently GenBank contains over 6500 TPA records, with the top organisms being Drosophila melanogaster (2200 sequences), Homo sapiens (990), Oryza sativa (640) and Mus musculus (350).
How do I do an advanced search on PubMed?
To search by author using the search builder, click Advanced search and then select Author from the All Fields menu. The author search box includes an autocomplete feature. You may click an author link on the abstract display to execute a search for the author in PubMed.
How to see the revision history of a sequence?
GenBank can show the revision history of a sequence. The revision history shows the various GI numbers, version numbers, and update dates for sequences that appeared in a specific GenBank record. To see the revision history of a sequence, append report=girevhist to the record’s URL.
What kind of database is the GenBank database?
GenBank. The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations. This database is produced and maintained by the National Center for Biotechnology Information (NCBI) as part of the International Nucleotide Sequence Database Collaboration (INSDC).
How does a GenBank sequence get released to the public?
Upon receipt of a sequence submission, the GenBank staff examines the originality of the data and assigns an accession number to the sequence and performs quality assurance checks. The submissions are then released to the public database, where the entries are retrievable by Entrez or downloadable by FTP.
How to search for annotated sample GenBank records?
An annotated sample GenBank record for a Saccharomyces cerevisiae gene demonstrates many of the features of the GenBank flat file format. There are several ways to search and retrieve data from GenBank. Search GenBank for sequence identifiers and annotations with Entrez Nucleotide.
