Introduction of DNA into cells by exposing to high voltage electric pulse 

  1. Electrofusion

  2. Electrofission

  3. Electrolysis

  4. Electroporation


Correct Option: D

In which of the following method, foreign DNA is coated on the tungsten particle?

  1. Microprojectile gun method

  2. Microinjection method

  3. Liposome-mediated gene transfer

  4. None of the above


Correct Option: A
Explanation:
Microprojectile gun method is a device for delivering exogenous DNA to cells. Here, the impregnation of the cells with nucleic acid or with other biological molecules is achieved by coating the molecules that are intended to be introduced in to the cells on to micro carriers which generally is high density tungsten micro particles.
Microinjection is a technique of delivering foreign DNA into a living cell through a glass micropipette.
Liposome-mediated gene transfer is cell-type-specific gene transfer vehicles in vitro and in vivo using liposome.
so, the correct answer is option A.

Which of the following is used as a reporter gene?

  1. lacZ gene

  2. Green fluorescent protein

  3. Nif gene

  4. Both A and B


Correct Option: D

Which of the following is needed for gene transformation and its screening in animals?

  1. Foreign DNA

  2. Plasmid

  3. Selectable marker

  4. All of the above


Correct Option: D

Which of the following can minimizes the ethical issues of animal biotechnology?

  1. Biopatent

  2. Ban on experimental use of animals

  3. Create new species only for experiments

  4. Both A and B


Correct Option: D

Which of the following principle is associated with the ethics of animal use in genetic engineering?

  1. Reduction of animal use

  2. Refinement of husbandry

  3. Replacement of animal with non-animal alternatives

  4. All of the above


Correct Option: D

Which of the following is more sufferer?

  1. Native animals

  2. Transgenic animals

Which of the following is used as probiotic?

  1. Rhizobium

  2. Lactobacillus

  3. E. coli

  4. Streptomyces


Correct Option: B
Explanation:

Lactobacillus acidophilus is a type of bacteria found in your intestines.

 Lactobacilli, particularly L. acidophilus, are often used as probiotics
The World Health Organization defines probiotics as "live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host."

.......... was produced by the slaughtering of the pig but now it is stopped due to genetic engineering.

  1. Meat

  2. Insulin

  3. Both A and B

  4. Fats


Correct Option: B
Explanation:

Animal insulin is derived from cows and pigs. Until the 1980s, animal insulin was the only treatment for insulin dependent diabetes. These days the use of animal insulin has largely been replaced by human insulin and human analogue insulin, however, animal insulin is still available on prescription.

Which of the following enzyme used in dairy industry is produced by GM microorganism?

  1. Peptidase

  2. Chymosin

  3. Bovine

  4. None of the above


Correct Option: B
Explanation:

Chymosin, commonly known as rennin, is the principal milk- coagulating enzyme present in rennet. Rennet, which has a long and extensive history of safe use in making cheese and other dairy products.
