NCO recombinants are thought to occur primarily by the Synthesis Dependent Strand Annealing (SDSA) model, illustrated on the left. Most recombination events appear to be the SDSA type. Genetic recombination (also known as genetic reshuffling ) is the exchange of genetic material between different organisms which leads to production of offspring ...
The antibody test (ELISA or western blot) uses a recombinant HIV protein to test for the presence of antibodies that the body has produced in response to an HIV infection. The DNA test looks for the presence of HIV genetic material using reverse transcription polymerase chain reaction (RT-PCR). Development of the RT-PCR test was made possible ...
Gene conversion is the process by which one DNA sequence replaces a homologous sequence such that the sequences become identical after the conversion. [1] Gene conversion can be either allelic, meaning that one allele of the same gene replaces another allele, or ectopic, meaning that one paralogous DNA sequence converts another.
These new combinations of DNA represent genetic variation in offspring, which in turn enables populations to adapt during the course of evolution. [2] Homologous recombination is also used in horizontal gene transfer to exchange genetic material between different strains and species of bacteria and viruses. Horizontal gene transfer is the ...
The final result of conjugation, transduction, and/or transformation is the production of genetic recombinants, individuals that carry not only the genes they inherited from their parent cells but also the genes introduced to their genomes by conjugation, transduction, and/or transformation.

Molecular cloning is one of the most commonly used procedures in molecular biology. A gene of interest may be inserted into a plasmid vector via ligation, and the plasmid is then transformed into Escherichia coli cells. However, not all the plasmids transformed into cells may contain the desired gene insert, and checking each individual colony ...
Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
The following is a list of notable proteins that are produced from recombinant DNA, using biomolecular engineering. [1] In many cases, recombinant human proteins have replaced the original animal-derived version used in medicine.
