The answer is helicase. These are a class of enzymes important
to all living organisms. Their chief purpose is to unzip an organism's
genes. They are motor proteins that travel directionally alongside
a nucleic
acid phosphodiester backbone, unravelling two annealed nucleic acid using energy
consequential from ATP hydrolysis.
Genetic engineering is the process of cutting DNA into fragments and inserting the fragments with a desired gene into another organism of the same or different species
