Answer:
Option A. It is produced in vitro
Explanation:
The technique of DNA vaccine involves transfer of genetically engineered or modified form of DNA into body directly with the help of injection. The DNA codes for protein, that protein is antigen and thus provides immunity.
The DNA vaccine can be produced at a low cost and easy to purify. The DNA vaccines are produced in-vivo not in-vitro, so Option A is not a characteristic of DNA Vaccine.
Answer:
increasing pressure inside the lymph capillary
Explanation:
Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.
The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.
The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.
When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.
Thus, the selected option is the correct answer.
