Question:18
Answer:
Vaccination works on the principle of 'memory' of the immune system. Vaccines help the immune system to fight future attacks from a pathogen. Antibodies are created by the body in response to the vaccine, and these antibodies jump into action when the pathogen attacks again. Yeast is used to producing the Hepatitis B vaccine.
Question:19
Uncontrolled cell division which leads to the formation of a tumour is called cancer. Unlike a normal cell, which loses its ability to divide in a few iterations, cancer cells continue to divide endlessly. Generally, the normal cell stops diving when it comes in contact with other cells. This ability is known as contact inhibition, and cancerous cells are abnormal as they do not possess this ability.
Question:20
Answer:
This condition is called allergy. Such a reaction is caused by mast cells; and basophils (white blood cells). To prevent such allergic reactions, one should avoid the substances to which they are allergic. Allergies against pollen are very common, and an allergic person should avoid going near such flowers.
Question:21
For an organ transplant, it is an advantage to have an identical twin. Why?

High level of surveillance.
Reporting of any new case within 14 days.
To cover all the children below age 5, Polio booths are established throughout the country and volunteers are hired to administer the polio vaccine.
OPV (Oral Polio Vaccine): OPV is an attenuated vaccine, which is produced at a sub-physiological temperature by the passage of the virus through non-human cells. This produces spontaneous mutation in the viral genome. A single vial of OPV usually contains 10-20 doses.
India was declared a Polio free nation on 27th March 2014 as there were no new cases in the previous three years.
Question:8
What are recombinant DNA vaccines? Give two examples of such vaccines. Discuss their advantages.
Answer:
In recombinant DNA vaccine, only one or two antigen is inserted into the DNA of a suitable host. Recombinant DNA technology enables to make vaccines on a larger scale with least chances of contamination. These are cheaper. Examples include Hepatitis B and HPV Vaccine
Cell culture is used to do large scale production. A suitable animal (ex - horse) is injected with strains of pathogen and antigens are produced in the horse's cells. Antigens are then extracted from horse's serum. However, there are many shortcomings to this method –
Due to the possibility of contamination, there are chances of contracting other diseases
The method is challenged by Animal Rights Activists.
Recombinant DNA technology can address these issues as yeast is required to produce the vaccine, and large scale production can be done at a lower cost.
