Genetic engineering

Genetic engineering

The science of modifying and manipulating genes to create new artificial DNA or synthetic genes of different organisms. There are many purposes for genetic engineering, some of which include finding better treatment for diseases, or simply for discovering new organism of interest.

Genetic engineering

marker-assisted introgression

Biotechnology; Genetic engineering

The use of DNA markers to increase the speed and efficiency of introgression (q.v.) of a new gene or genes into a population. The markers will be closely linked to the gene(s) in question.

DNA diagnosis

Biotechnology; Genetic engineering

The use of DNA polymorphisms to detect the presence of a specific allele (often associated with a disease or syndrome) or DNA sequence.

fluorescence-activated cell sorting (FACS)

Biotechnology; Genetic engineering

The use of laser beams to detect differences in fluorescence between different types of cells in a mixture, and the subsequent deflection of cells into separate bins corresponding to each type of ...

allele-specific amplification (ASA)

Biotechnology; Genetic engineering

The use of polymerase chain reaction (PCR) at a sufficiently high stringency that only a primer with exactly the same sequence as the target DNA will be amplified. A powerful means of genotyping for ...
