LIFE SCIENCE

Detailed explanation-1: -The use of bacteria as a vector for the delivery of therapeutic genes to target cells is known as bactofection, and several studies have used this approach to deliver genes encoding anti-angiogenic molecules to tumor cells in vivo.

Detailed explanation-2: -Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. In the laboratory, plasmids may be introduced into a cell via transformation. Synthetic plasmids are available for procurement over the internet.

Detailed explanation-3: -After the foreign gene is inserted, another enzyme, called a ligase, is used to sew the plasmid together. Plasmids are ideal vectors for carrying the new gene into a host cell, because, in nature, plasmids are routinely passed from one bacterium to another, where they are readily accepted.
