  1. treated bacteria or viruses or one of their proteins

  2. MHC proteins

  3. the same as monoclonal antibodies

  4. all of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. 


So, the correct option is 'Option A'.

A vaccine is usually given?

  1. At any time

  2. At the time disease causing germs enters the body

  3. Before the symptoms of the disease appeared

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A vaccine is a biological preparation that provides acquired immunity to a particular disease. Vaccines are made from microbes. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine. The antibodies created will be the same as those produced if the person was exposed to the pathogen. When the vaccinated person comes into contact with the disease-causing microbe, the antibodies recognize the pathogen and act against to it. Hence, the vaccine should be given before attacking of the disease. 

So, the correct answer is option C.

At present, animal cell culture technology is extensively used for the production of 

  1. Chylomicrons

  2. Antibiotics

  3. Vaccines

  4. Edible proteins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The animal cell lines are cultured in the laboratory on the artificial media which requires a specific temperature. Biological products produced by recombinant DNA (rDNA) technology in animal cell cultures include enzymes, synthetic hormones, immunobiological (monoclonal antibodies, interleukins, lymphokines), and anticancer agents.

So, the correct answer is option C.

What is a vaccine?

  1. Treated bacteria, virus or protein

  2. Treated algae

  3. Activated fungi

  4. Plant preparation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A vaccine is a biological preparation which provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened (attenuated) or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it and keep a record of it so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Thus, the correct answer is option A.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Lactobacillus promotes curdling of milk by creating an acidic environment. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. It is made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. Human malaria is transmitted only by females of the genus Anopheles. Dengue is spread through the bite of the female mosquito (Aedes aegypti). Kharif crops are those crops which are grown in monsoon season from the month of June to September. They need more water than rabi crops for their growth and development. Broadcasting is the method of random scattering of seeds on the surface of the seedbed. It can be done manually or mechanically.

So, the correct answer is option D.
