FASTA format DNA and protein sequence alignment

Files with fasta file extension can be usually found as DNA and protein sequence data files in FASTA format.

Further details

The fasta file extension is related to a FASTA format that does not contain the chromatogram but only the sequence string (it is much more simple format).

The FASTA programs find regions of local or global (new) similarity between Protein or DNA sequences, either by searching Protein or DNA databases, or by identifying local duplications within a sequence.

Other programs provide information on the statistical significance of an alignment. Like BLAST, FASTA can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

What file extension actually is?

Simply put, file extensions are the characters after the dot in the computer file name, so for example document-name.pdf has file extension „pdf“. This helps Windows to identify which program should be used to open the file.
