Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.

Jan 16, 2025 · New! Introducing the Multiple Comparative Genome Viewer (MCGV) Beta Release. Jan 16, 2025. NLM’s NCBI is excited to introduce the Multiple Comparative Genome Viewer (MCGV), a new tool in active development that allows you to visualize an alignment of multiple eukaryotic genomes.

Search all biomedical databases provided by the National Center for Biotechnology Information (NCBI), an agency of the U.S. National Library of Medicine at the NIH

PubMed® comprises more than 38 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full text content from PubMed Central and publisher web sites.

The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.

Welcome to NCBI. The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

NCBI's Genome resources include information on large-scale genomics projects, genome sequences and assemblies, and mapped annotations, such as variations, markers and data from epigenomics studies.
