GenBank:
An annotated collection of all
publicly available nucleotide and amino acid sequences.
EST database:
A collection of expressed
sequence tags, or short, single-pass sequence reads from mRNA (cDNA).
GSS database:
A database of genome survey
sequences, or short, single pass genomic sequences.
HTG database:
A collection of high
throughput genome sequences from large-scale genome sequencing centers;
including unfinished and finished sequences.
SNPs database:
A central repository for both
single base nucleotide substitutions and short deletion and insertion
polymorphisms.
RefSeq:
A database of non-redundant
reference sequences standards, including genomic DNA contigs, mRNAs and
proteins for known genes. Multiple collaborations, both within
NCBI and with external groups, support our data-gathering efforts.
STS database:
A database of sequence tagged
sites; or short sequences that are operationally unique in the genome.
UniSTS:
A unified, non-redundant view
of sequence tagged sites (STSs).
UniGene:
A collection of ESTs and
full-length mRNA sequences organized into clusters, each representing a unique
known or putative human
gene annotated with mapping and expression information and cross-references to
other sources.
