Introduction to bioinformatics

1. Introduction to Bioinformatics

2. What is Bioinformatics?What is Bioinformatics?
Bioinformatics is an integration of computer science,
mathematical and statistical methods to manage and
analyze the biological information.
Computational biology and bioinformatics is an
interdisciplinary field that develops and applies
computational methods to analyze large collections of
biological data, such as genetic sequences, cell
populations or protein samples, to make new
predictions or discover new biology.

3. Goals of BioinformaticsGoals of Bioinformatics
The most important task in bioinformatics is to analyze the sequence
information. This process is called computational biology that
involves,

Finding genes in DNA sequence of various organisms.

Developing methods to predict the structure and function of newly
discovered protein and structural RNA sequences.

Clustering of protein sequences in to families.

Developing protein models.

Aligning of similar protein.

Generating phylogenetic tress to examine evolutionary relation
ships.

5. Main areas of Bioinformatics…..

31. Timeline of Bioinformatics
l
1955- Bovine insulin is the 1st
protein to be sequenced.
l
1965- Atlas of protein sequence
and structure by Margarat Day
hoff et al was a printed book.
l
1978- the term 'bioinformatics'
coined.
l
1986- The term "Genomics"
appeared for the first time to
describe the scientific discipline of
mapping, sequencing, and
analyzing genes. The term was
coined by Thomas Roderick.
l
The SWISS-PROT database was
created.
l
The PCR reaction was described
by Kary Mullis and co-workers.

1987- The use of yeast artifical
chromosomes
l
The physical map of E. coli was
published.
l
1988 - National Center for
Biotechnology Information
(NCBI) created.
l
The Human Genome Initiative
was started.
l
1990 - The BLAST program was
implemented.
