Recombinant DNA
Recombinant DNA is a form of artificial
DNA which is engineered through the combination or insertion of one or more DNA strands, thereby combining DNA sequences which would not normally occur together. In terms of
genetic modification, recombinant DNA is produced through the addition of relevant DNA into an existing organismal
genome, such as the
plasmid of bacteria, to code for or alter different traits for a specific purpose, such as immunity. It differs from
genetic recombination, in that it does not occur through processes within the cell or ribosome, but is exclusively engineered.

recombinant DNA technology
Noun
1. the technology of preparing recombinant DNA in vitro by cutting up DNA molecules and splicing together fragments from more than one organism
(synonym) genetic engineering, gene-splicing
(hypernym) biotechnology
Recombinant DNA technology
A series of procedures used to join together (recombine) DNA segments. A recombinant DNA molecule is constructed (recombined) from segments from 2 or more different DNA molecules. Under certain conditions, a recombinant DNA molecule can enter a cell and replicate there, autonomously (on its own) or after it has become integrated into a chromosome.
genetic engineering (bioengineering, gene splicing, medical biotechnology, the new biotechnology, rDNA technology, recombinant DNA technology)
Altering genetic (DNA) molecules outside an organism (e.g., by inserting into a DNA molecule a segment from a very different DNA molecule) and making the resultant DNA molecules (called “recombinant DNA”) function in living things.
