Synthetic Genomes
Synthetic genome is a synthetically built genome whose formation involves either genetic modification on pre-existing life forms or artificial gene synthesis to create new DNA or entire lifeforms. The field that studies synthetic genomes is called synthetic genomics. Recombinant DNA technology Soon after the discovery of Restriction enzyme, restriction endonucleases and ligases, the field of genetics began using these molecular tools to assemble artificial sequences from smaller fragments of synthetic or naturally occurring DNA. The advantage in using the recombinatory approach as opposed to continual DNA synthesis stems from the inverse relationship that exists between synthetic DNA length and percent purity of that synthetic length. In other words, as you synthesize longer sequences, the number of error-containing clones increases due to the inherent error rates of current technologies. Although recombinant DNA technology is more commonly used in the construction of fusion protei ...

Genetic Modification
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can either be inserted randomly or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modif ...
