What is genomics all about ?
Study of the genome is called genomics. It includes a search for the genes in the total three billion basic units of the DNA (nucleotides) that comprise the human genome. In other words, the goal of genome research is to identify the regions of the genome that make up genes and control regions from the vast amounts of junk DNA. Alongside this, the researchers want to know the function of each gene. For example, which gene causes a particular cell to start multiplying ceaselessly, causing cancer, why different people show different reactions to a given situation etc. Once we understand these things, it will be possible to design better drugs, safer chemicals, and also the tools for gene therapy.
