Answer 1

16. This technique is a type of artificial cloning , and this technique is known as gene cloning or molecular cloning. In this technique, copies of a particular genes or DNA are produced using genetic engineering.

The targeted Gene is inserted into the bacterial plasmid which is circular bacterial DNA.then the plasmid is introduced into the bacteria through the process of transformation then with the help of selectable markers , transformed bacteria are selected .
