Bioinformatics is defined as the field that studies biology using computers and information technology. It involves the collection, storage, and analysis of molecular biological data using techniques from computer science and statistics. Some key events in bioinformatics include Watson and Crick proposing the DNA double helix structure in 1953, and the development of sequence alignment and structure prediction algorithms in the 1970s. Bioinformatics aims to better understand living cells at the molecular level by analyzing raw molecular sequence and structure data. It provides globally accessible databases and analysis tools to enable sharing and study of biological data.

YEAR DISCOVERY/INVENTION AND ITS SIGNIFICANCE
1953
Watson and Crick proposed the DOUBLE HELIX structure of the genetic
material
1965
The first major bioinformatics project was undertaken by Margaret Dayhoff
in1965, who developed a first protein sequence database called Atlas of
Protein Sequence and Structure
1970
Brookhaven National Laboratory established the Protein Data Bank for
archiving three-dimensional protein structures
1970
The first sequence alignment algorithm was developed by Needleman and
Wunsch
1974
The first protein structure prediction algorithm was developed by Chou and
Fasman
1980
GenBank and the development of fast database searching algorithms such as
FASTA by William Pearson and BLAST by Stephen Altschul and coworkers.

6. GOALS
The ultimate goal of bioinformatics is to better understand
a living cell and how it functions at the molecular level
Analyzing raw molecular sequence and structural data,
bioinformatics research can generate new insights and
provide a “global” perspective of the cell.

7. WHY BIOINFORMATICS?
Number of researches increasing every day
Explosive growth in biological information
Need for a huge database to store, manage and retrieve
information
Regular updating
Available online to all
Without these most of the medical and biological field
would have been on standstill
