Detailed explanation-1: -Using recombinant DNA technology to modify an organism’s DNA to achieve desirable traits is called genetic engineering. Addition of foreign DNA in the form of recombinant DNA vectors that are generated by molecular cloning is the most common method of genetic engineering.
Detailed explanation-2: -Recombinant DNA technology involves transferring genes from one organism to another, or changing genes in an organism by altering their DNA to produce a desired product. Genetic modification involves altering an organisms characteristics (DNA) by the use of genetic engineering.
Detailed explanation-3: -For this task, the genetic engineer uses a restriction enzyme. These enzymes recognize specific nucleotide sequences and cut the DNA at precisely those points. It is these enzymes that allow researchers to snip a gene out of the DNA sequence from one organism and splice it into the DNA of another.
