Detailed explanation-1: -Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
Detailed explanation-2: -Recombinant DNA: DNA which has been altered from its original form by joining genetic material from two different sources. It usually involves putting a gene or part of a gene obtained from one organism into the genome of a different organism.
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.
