I am interested in Bioinformatics.

Bioinformatics is the combination of Molecular Biology (genes 'n stuff) that I studied in my PhD and Information Technology.
The biological code of life is DNA, this is made up of four different nucleotides:

C G T A

This is translated (via mRNA) into a chain of amino acids which are called proteins.

For example:

ATG

is coded into the amino acid:

Met

Methionine (Met) is the start codon (the amino acid that starts the chain of amino acids).

3D representation of the protein myoglobin: this protein stores and releases oxygen in muscle cells

Proteins

These are long chains of amino acids wrapped up into a certain shape to give it a function. Proteins are mostly enzymes which are little machines that do stuff in the cell and make it work.

Why is it useful to do Bioinformatics?

If we can work out why people are different due to the different sequences of their DNA, we have very valuable information (eg. why some people get infected by a particular strain of the cold virus and other people don't)- that's where the IT comes into it!
