Detailed explanation-1: -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. For example, genetic engineering may involve adding a gene from one species to an organism from a different species to produce a desired trait.

Detailed explanation-2: -the science of heredity. When genetic information is moved from one cell to another to change the characteristics of the cell, the procedure is known as genetic: engineering. Changing a characteristic by removing and inserting genes into DNA is known as gene: splicing.

Detailed explanation-3: -Gene transfer therapy introduces new genetic material into cells. If an altered gene causes a necessary protein to be faulty or missing, gene transfer therapy can introduce a normal copy of the gene to recover the function of the protein.

Detailed explanation-4: -Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

Detailed explanation-5: -Cut open the plasmid and “paste” in the gene. This process relies on restriction enzymes (which cut DNA) and DNA ligase (which joins DNA). Insert the plasmid into bacteria. Grow up lots of plasmid-carrying bacteria and use them as “factories” to make the protein.
