Bioinformatics is a subdiscipline of biology/computer science concerned with the acquisition, storage, analysis, and dissemination of biological data. This helps organize and determine nucleotides of a given DNA molecule from known data about biological data through computer sustems.
** The Human Genome Project increased speed of DNA sequencing and lowered the cost. Basically made it more efficent.
