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: -Transgene: A gene from one organism inserted into another organism by recombinant DNA techniques. Transgenic organism: An organism resulting from the insertion of genetic material from another organism using recombinant DNA techniques.
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.
