An Introduction to Bioinformatics On-line
Bioinformatics is a relatively new branch of cell and molecular biology which involves the use of computers and the internet to bank, search and analyse nucleic acid and protein sequences. There are several basic areas within this field: (see below) Click for more information
Sequence Databases
(Genbank, EMBL)
>Banking and Searching Sequences
>Linking sequence information to literature references and other
related sequences
>Linking sequence information to X-Ray chrystalographic structures
Sequence Analysis (On-line
analysis Programs)
>Alignment of sequences for discovering structural and evolutionary
relationships
>Prediction of secondary and tertiary structure (proteins) based on
primary sequence
>Prediction of protein physical properties (pI, titration curve,
molecular mass)
>Identification of specific features (motifs) for glycosylation,
phosporylation, protein-protein interaction
>Translation of nucleic acid sequences into amino acid sequences
>Identification of nucleic acid motifs; promoter elements, start
codons, termination codons, introns etc.
>Design of PCR primers
>Assembly of "contigs" into contiuous sequences for
determining genome structure
Higher order modeling of
protein structure (Computational Bioinformatics)
>Analysis of free energy content for projected protein folds etc.
>Homology Modeling: "threading (superimposing) one sequence over a related
sequence
