Answer: False

Explanation: The COMPLEMENT SYSTEM consists of proteins synthesized in the liver. They are activated by inespecific harmful substance (antigen) and begins a cascade of proteins that finally forms an attack complex against bacteria.

The COMPLEMENT is part of the INNATE IMMUNITY, because it is an inherent response, something all humans born with, and it is part of the first defense barrier against any antigen. Part of the innate immunity are too: natural killer cells, neutrophils, monocytes, dendritic cells and macrophages.

On the other hand, the ADAPTATIVE IMMUNITY, is the response that the body develops after being exposed to an antigen before. It is like something that the body recognizes, and then "learns" how to act against it. Part of the adaptative immunity are: lymphocyte T and B, and the antibodies (substances called Immunoglobulins). The immunoglobulins (Ig) are glycoproteins present in the blood.

xenn [34]

Answer:

The correct option is <em>A) Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide.</em>

Explanation:

The DNA can be easily cloned by the help of vectors like plasmids. Plasmids can be described as an extra-chromosomal ring which is present in bacteria. The plasmid has many multiple cloning sites where the desired DNA can be incorporated. the plasmid with the foreign DNA is then incorporated back into a bacterial cell. As bacterial cells like E.coli divide in a short period of time, many copied of our DNA could be obtained whenever the bacterial cell replicates.
