Genetic engineering is called genetic modification its mean add more new DNA to an organisms.In every living thing all use the same DNA made of
TACG.Today is genetic engineering is used for food,medicine,research.Genetic engineering is combining DNA from two or more
organisms then the DNA become
recombinant DNA.Scientist figure out that is two types of enzymes restriction and ligase,In restriction enzymes cut the DNA and In ligase enzymes,enzymes attache the piece of DNA together.Restriction enzymes
are cut DNA sequence and the end is sticky ends.Genetic engineering has been used in medicine and also used to human albumin,monoclonal antibodies, antihemophilic factors.In genetic engineering human cell is the production of insulin.In genetic engineering plasmid is isolated from
a bacterium then enzymes cut the DNA at specific slide the plasmid is inserted back into the bacterium then the new gene direct to a bacterium and then make a new protein product is called interferon.
