Answer:
Genetic engineering is a process through which the genome of an organism is manipulated.
By recombinant DNA technology, we can manipulate the genome of bacteria and produce vital enzymes from it.
First of all, we select the genes for our desired protein or enzyme production. We cut the gene through specific restriction enzymes. The same restriction enzymes are used to cut a vector such as a plasmid. Then the gene of interest is placed into the plasmid. The plasmid or vactor is injected into a bacteria. As a result, the bacteria makes multiple copies of the gene and hence enzyme can be produced from it.

Answer;
A. the place on Earth's surface directly above the focus
An earthquake's epicenter is the place on Earth's surface directly above the focus.
Explanation;
-Epicenter is the point on the surface of the Earth that lies directly above the hypocenter or the focus of the earthquake. A hypocenter or the focus of the earthquake is the place within the earth where rock ruptures and slips, or the place where an explosion occurs. An earthquake is an episode of ground shaking.
