This allows a sequence that was obtained from a database to be labelled with a reference to its database record. The database identifier format is understood by the NCBI tools like makeblastdb and table2asn. The following list describes the NCBI FASTA defined format for sequence identifiers. [9]
Linking and profiling sequence alignment data from NCBI-BLAST results with major sequence analysis servers/services: Nucleotide, peptide: 2010 SAM Local and global search with profile Hidden Markov models, more sensitive than PSI-BLAST: Both: Karplus K, Krogh A [15] 1999 SSEARCH Smith-Waterman search, slower but more sensitive than FASTA: Both ...
FASTA is a DNA and protein sequence alignment software package first described by David J. Lipman and William R. Pearson in 1985. [1] Its legacy is the FASTA format which is now ubiquitous in bioinformatics .
The NCBI assigns a unique identifier (taxonomy ID number) to each species of organism. [5] The NCBI has software tools that are available through web browsers or by FTP. For example, BLAST is a sequence similarity searching program. BLAST can do sequence comparisons against the GenBank DNA database in less than 15 seconds.
When working with a known species, and looking to sequence a gene at an unknown location, BLAST can compare the chromosomal position of the sequence of interest, to relevant sequences in the database(s). NCBI has a "Magic-BLAST" tool built around BLAST for this purpose. [31] Comparison
UniProt is a freely accessible database of protein sequence and functional information, many entries being derived from genome sequencing projects.It contains a large amount of information about the biological function of proteins derived from the research literature.

A FASTQ file has four line-separated fields per sequence: Field 1 begins with a '@' character and is followed by a sequence identifier and an optional description (like a FASTA title line). Field 2 is the raw sequence letters. Field 3 begins with a '+' character and is optionally followed by the same sequence identifier (and any description) again.
