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

In 1975, he and Alan Coulson published a sequencing procedure using DNA polymerase with radiolabelled nucleotides that he called the Plus and Minus technique.

In addition to his seminal work on the amino acid sequence of insulin, Frederick Sanger and his colleagues played a key role in the development of DNA sequencing techniques that enabled the establishment of comprehensive genome sequencing projects. DNA-sequencing technology developed ДЇrederick Sanger and Walter Gilbert shared half of the 1980 Nobel Prize in Chemistry for Independently developing methods for the sequencing of DNA. 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 base pairs ) and Simian virus 40 in 19, respectively. In 1972, Walter Fiers and his team at the Laboratory of Molecular Biology of the University of Ghent ( Ghent, Belgium) were the first to determine the sequence of a gene: the gene for Bacteriophage MS2 coat protein.

Extending this work, Marshall Nirenberg and Philip Leder revealed the triplet nature of the genetic code and were able to determine the sequences of 54 out of 64 codons in their experiments. Holley and colleagues published the first nucleic acid sequence ever determined, the ribonucleotide sequence of alanine transfer RNA.

Watson and Francis Crick's publication of the structure of DNA in 1953 and Fred Sanger's publication of the Amino acid sequence of insulin in 1955, nucleic acid sequencing became a major target of early molecular biologists. Early sequencing efforts ДЇollowing Rosalind Franklin's confirmation of the helical structure of DNA, James D. While the word genome (from the German Genom, attributed to Hans Winkler) was in use in English as early as 1926, the term genomics was coined by Tom Roderick, a geneticist at the Jackson Laboratory ( Bar Harbor, Maine), over beer at a meeting held in Maryland on the mapping of the human genome in 1986.

4.3 Population and conservation genomicsДЇrom the Greek О“О•Оќ gen, 'gene' (gamma, epsilon, nu, epsilon) meaning 'become, create, creation, birth', and subsequent variants: genealogy, genesis, genetics, genic, genomere, genotype, genus etc.

4.2 Synthetic biology and bioengineering.

1.3 DNA-sequencing technology developed.

The field also includes studies of intragenomic (within the genome) phenomena such as epistasis (effect of one gene on another), pleiotropy (one gene affecting more than one trait), heterosis (hybrid vigour), and other interactions between loci and alleles within the genome. Advances in genomics have triggered a revolution in discovery-based research and systems biology to facilitate understanding of even the most complex biological systems such as the brain. Genomics also involves the sequencing and analysis of genomes through uses of high throughput DNA sequencing and bioinformatics to assemble and analyze the function and structure of entire genomes. In turn, proteins make up body structures such as organs and tissues as well as control chemical reactions and carry signals between cells. Genes may direct the production of proteins with the assistance of enzymes and messenger molecules. 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 all of an organism's genes, their interrelations and influence on the organism. A genome is an organism's complete set of DNA, including all of its genes. Genomics is an interdisciplinary field of biology focusing on the structure, function, evolution, mapping, and editing of genomes.
