FASTA Meaning and
Definition
-
FASTA is a widely used file format in bioinformatics for the representation of nucleotide or amino acid sequences. It is named after the initial letters of "FAST-All" as it was designed to enable quick and efficient sequence similarity searches. FASTA files usually have a .fasta extension and consist of a sequence identifier line followed by the corresponding sequence. The identifier line starts with a greater-than sign (>) and contains information such as the name of the sequence or the source from which it was obtained.
The primary purpose of the FASTA format is to facilitate sequence database searching and sequence alignment algorithms. It allows for easy storage and retrieval of large amounts of sequence data. FASTA can be used to compare a query sequence to a database of sequences, identify similar regions or motifs, and determine evolutionary relationships. It is compatible with various bioinformatics tools and can be easily parsed and manipulated to extract specific information.
Moreover, the flexibility of FASTA allows for the inclusion of additional information, such as keywords and comments, in the sequence identifier line. This provides a means for researchers to annotate and categorize sequences, enhancing the organization and accessibility of sequence databases. FASTA has become a standard format in bioinformatics due to its simplicity, versatility, and long-standing usage across various applications and algorithms.
