It involves the use of computational techniques and tools to gather, process, and extract meaningful information from large sets of biological data.
Three commonly used tools in bioinformatics are:
- BLAST (Basic Local Alignment Search Tool):
- Function: BLAST is used for comparing biological sequences, such as DNA, RNA, or protein sequences, against a database to identify similar sequences.
- Application: It helps in sequence alignment, finding homologous genes, and annotating unknown sequences by comparing them to a vast database of known genetic information.
- NCBI Entrez Utilities:
- Function: Entrez is a set of search and retrieval tools provided by the National Center for Biotechnology Information (NCBI). It includes various databases such as PubMed, GenBank, and others.
- Application: Researchers use Entrez tools to search and retrieve information from databases like nucleotide sequences, protein structures, and literature, facilitating comprehensive exploration of biological data.
- BioPython:
- Function: BioPython is an open-source collection of Python tools for computational biology and bioinformatics. It provides modules and classes for various biological data manipulation tasks.
- Application: BioPython is used for tasks like reading and writing different sequence file formats, performing sequence alignments, accessing online biological databases, and conducting analyses with ease using the Python programming language.
These tools play a crucial role in tasks such as sequence analysis, structural biology, functional genomics, and other areas of biological research by enabling efficient handling and interpretation of vast amounts of biological data.
