‘Bioinformatics’ is the branch of research science that involves the development of computational tools and databases for better understanding the living organisms. Bioinformatics is limited to sequence, structural and functional analyses of genes, genomes and their products. It differs from a related field ‘computational biology’ that includes all biological areas that involve computation.
‘Genomics’ is the study of the genome of an organism involving the simultaneous analysis of a large number of genes using automated data gathering tools. Genomics includes various fields such as genome mapping, sequencing, functional genomics and comparative genomics. The advent of genomics and the rapid explosion of sequence information have enormously led to the development of bio-informatics. Genomics involves the systematic use of genome information and associates with other data providing solutions in biology, medicine and industry. Genomics has the potential of offering new therapeutics and diagnostics.
‘Proteomics’ is the study of the proteome. ‘Proteome’ refers to the entire set of proteins that are expressed in a cell. Proteomics involves the simultaneous analysis of all the translated proteins in a cell and includes their identification, quantification, localization, modifications, interaction and functions.
