.FA File

The fa file extension is typically  used for a special FASTA DNA format used in biochemistry.

The fa file does not contains 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.

Files with fa file extension can be usually encountered as data files in a special FASTA DNA format used in biochemistry.

How to open:

Some specialized biochemistry programs support all kinds of FASTA formats.

How to convert:

You will need a special converter if you need to export these files to some kiind of exchange format or transfer it to another software.
