Articles relating to genetic engineering, the direct manipulation of an organism's genes using biotechnology.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.
Genetic engineering techniques allow the modification of animal and plant genomes. Techniques have been devised to insert, delete, and modify DNA at multiple levels, ranging from a specific base pair in a specific gene to entire genes. There are a number of steps that are followed before a genetically modified organism (GMO) is created.
The iGEM (International Genetically Engineered Machine) competition is a worldwide synthetic biology competition that was initially aimed at undergraduate and 'overgraduate' university students, but has since expanded to include divisions for high school students, entrepreneurs, and community laboratories. iGEM is presented as "the heart of synthetic biology" - educating the next generation of ...
Reverse genetics is a method in molecular genetics that is used to help understand the function(s) of a gene by analysing the phenotypic effects caused by genetically engineering specific nucleic acid sequences within the gene. The process proceeds in the opposite direction to forward genetic screens of classical genetics.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". [1]
Human germline engineering has two potential applications: prevent genetic disorders from passing to descendants, and to modify traits such as height that are not disease related. For example, the Berlin Patient has a genetic mutation in the CCR5 gene that suppresses the expression of CCR5.
The technique builds on Mario Capecchi and Oliver Smithies' Nobel Prize–winning discovery that homologous recombination (HR), a natural hi-fidelity DNA repair mechanism, can be harnessed to perform precise genome alterations in mice. rAAV mediated genome-editing improves the efficiency of this technique to permit genome engineering in any pre ...
