• • • Genomics is an interdisciplinary field of science focusing on the structure, function, evolution, mapping, and editing of genomes. A genome is an organism's complete set of, including all of its genes. In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of genes, which direct the production of with the assistance of enzymes and messenger molecules. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genomics also involves the sequencing and analysis of genomes through uses of high throughput and to assemble and analyze the function and structure of entire genomes. Advances in genomics have triggered a revolution in discovery-based research and to facilitate understanding of even the most complex biological systems such as the brain.

The field also includes studies of intragenomic (within the genome) phenomena such as (effect of one gene on another), (one gene affecting more than one trait), (hybrid vigour), and other interactions between and within the genome.

While the word genome (from the Genom, attributed to ) was in use in as early as 1926, the term genomics was coined by Tom Roderick, a at the (), over beer at a meeting held in on the mapping of the human genome in 1986. Early sequencing efforts [ ] Following 's confirmation of the helical structure of DNA, and 's publication of the structure of DNA in 1953 and 's publication of the sequence of insulin in 1955, nucleic acid sequencing became a major target of early.

However, they differ substantially in terms of their engineering, sequencing chemistry, output (length of reads, number of sequences), accuracy and cost. Current commercial platforms include the 454 (Roche), Illumina (Illumina), SOLiD and Ion Torrent (Life Technologies), and PacBio (Pacific Biosciences) systems.

In 1964, and colleagues published the first nucleic acid sequence ever determined, the sequence of. Extending this work, and revealed the triplet nature of the and were able to determine the sequences of 54 out of 64 in their experiments. In 1972, and his team at the Laboratory of Molecular Biology of the (, ) were the first to determine the sequence of a gene: the gene for coat protein. Fiers' group expanded on their MS2 coat protein work, determining the complete nucleotide-sequence of bacteriophage MS2-RNA (whose genome encodes just four genes in 3569 [bp]) and in 1976 and 1978, respectively.

DNA-sequencing technology developed [ ]. And shared half of the 1980 Nobel Prize in chemistry for independently developing methods for the sequencing of DNA. In addition to his seminal work on the amino acid sequence of insulin, and his colleagues played a key role in the development of DNA sequencing techniques that enabled the establishment of comprehensive genome sequencing projects. In 1975, he and Alan Coulson published a sequencing procedure using DNA polymerase with radiolabelled nucleotides that he called the Plus and Minus technique.

This involved two closely related methods that generated short oligonucleotides with defined 3' termini. These could be fractionated by on a gel (called polyacrylamide gel electrophoresis) and visualised using autoradiography. The procedure could sequence up to 80 nucleotides in one go and was a big improvement, but was still very laborious.

Nevertheless, in 1977 his group was able to sequence most of the 5,386 nucleotides of the single-stranded, completing the first fully sequenced DNA-based genome. The refinement of the Plus and Minus method resulted in the chain-termination, or (see ), which formed the basis of the techniques of DNA sequencing, genome mapping, data storage, and bioinformatic analysis most widely used in the following quarter-century of research.
