This new recombinant DNA molecule can be cloned by being grown in bacteria cells. This is known as recombinant DNA technology. Duration: 1 minutes 12 seconds. A common technique in genetic engineering is to insert a new gene into a loop of bacterial DNA called a plasmid. "The molecular tool used to cut DNA is a restriction enzyme such as EcoR1. The enzyme has a precise shape that allows .

Recombinant therapeutics include proteins that help the body to fight infection or to carry out specific functions such as blood factors, hormones, growth factors, interferon's and interleukins. Starting with simple protein such as insulin (the first recombinant therapeutic product) and then growth hormone, recombinant biopharmaceuticals has increased considerably in recent years.

A DNA vaccine is a type of vaccine that transfects a specific antigencoding DNA sequence into the cells of an organism as a mechanism to induce an immune response.. DNA vaccines work by injecting genetically engineered plasmid containing the DNA sequence encoding the antigen(s) against which an immune response is sought, so the cells directly produce the antigen, thus causing a protective ...
