In bioinformatics and biochemistry, the FASTA format is a text-based format for representing either nucleotide sequences or amino acid (protein) sequences, in which nucleotides or amino acids are represented using single-letter codes. The format allows for sequence names and comments to precede the sequences.
The original FASTA program was designed for protein sequence similarity searching. Because of the exponentially expanding genetic information and the limited speed and memory of computers in the 1980s heuristic methods were introduced aligning a query sequence to entire data-bases.
The fourth is a great example of how interactive graphical tools enable a worker involved in sequence analysis to conveniently execute a variety if different computational tools to explore an alignment's phylogenetic implications; or, to predict the structure and functional properties of a specific sequence, e.g., comparative modelling.

Protein sequences can describe larger proteins and chemical language files such as mol files can describe simple peptides. But the complexity of new research biomolecules makes describing large complex molecules difficult with chemical formats, and peptide formats are not sufficiently flexible to describe non-natural amino acids and other ...
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.
Knowing the structure of a similar homologous sequence (for example a member of the same protein family) allows highly accurate prediction of the tertiary structure by homology modeling. If the full-length protein sequence is available, it is possible to estimate its general biophysical properties, such as its isoelectric point.
Biological sequence formats are a collection of file formats that are used in the biomedical sciences. There are a number of these. There are a number of these. Most of these formats were developed for use in particular programmes and have subsequently been reused by other programmes.
