What is Fasta in bioinformatics?
FASTA format is a text-based format for representing either nucleotide sequences or peptide sequences, in which base pairs or amino acids are represented using single-letter codes. A sequence in FASTA format begins with a single-line description, followed by lines of sequence data.
What is the NCBI?
The National Center for Biotechnology Information (NCBI) is a multi-disciplinary research group that serves as a resource for molecular biology information. It was formed in 1988 as a complement to the activities of the National Institutes of Health (NIH) and the National Library of Medicine (NLM).
What is the role of NCBI?
One of NCBI's roles is to maintain publicly available databases. But what exactly are databases, and why are they important for molecular biology? Basically, a database is a large and organized body of data. But one of the key criteria for a biological database is persistent data. In other words, the information encoded and represented by the data may change but the type of data is more resistant to change. This inflexibility of data is a reflection of what comprises macromolecules and how scientists have chosen to symbolize nature. For instance, the sequence of nucleic acids can be symbolized by letters representing nucleotides and a protein sequence can be represented by 20 letters symbolizing the amino acids. These strings of letter symbols constitute a staggering amount of information, but for computerized systems they can easily be organized and manipulated in an optimal way. A model sequence database is GenBank.
Why is NCBI important?
With input in mapping the human genome, NCBI's services are undeniably important. NCBI offers a comprehensive array of databases and software tools to analyze information. The advantage of having NCBI is that they offer a sizable quantity of accessible information to the public. NCBI continues the scientific tradition of making scientific knowledge free for all, which is an uncommon phenomenon in today's world of biotech companies and their closely guarded patents. Bioinformatics, as a discipline, continues to grow at an exponential rate. The NCBI currently combats the problem of redundancy of information by establishing non-redundant databases to limit search-times and increase the ease of making a query. The NCBI website currently handles its services efficiently, despite the overwhelming amount of services present. To continue this efficiency, NCBI must be aware of and receptive to new ways of assimilating data into an organized form
How does the NCBI combat redundancy?
The NCBI currently combats the problem of redundancy of information by establishing non-redundant databases to limit search-times and increase the ease of making a query. The NCBI website currently handles its services efficiently, despite the overwhelming amount of services present.

What is a model sequence database?
A model sequence database is GenBank. GenBank, a database containing all known nucleic acid sequences, is one of the members of the "Triple Entente" of sequence databases; the other two are the European Molecular Biology Laboratory (EMBL) and the DNA Database of Japan (DDBJ).

What is functional genomics?
Functional genomics assigns functional relevance to genomic information. It is the study of genes, their resulting proteins, and the role played by the proteins.
Basic Local Alignment Search Tool (BLAST)
The Basic Local Alignment Search Tool (BLAST) finds regions of similarity between sequences. The program compares nucleotide or protein sequences and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.
