  1. Bioinformatics

  2. Biotechnology

  3. Sustainable development

  4. Organic farming


Correct Option: B

Which of the following correctly defines a transgenic animal

  1. An animal which has foreign DNA and RNA in some of its cells because of an injection of DNA and RNA into the nucleus of the zygote from which it is developed

  2. An animal which has foreign DNA in all its cells because of an injection of DNA into the nucleus of the zygote from which it is developed

  3. An animal which has foreign DNA in some of its cells because of an injection of DNA into the nuclei of some of the cells of the blastocyst

  4. An animal which has foreign DNA in.all its cells because of an injection of DNA into the nuclei of some of the cells in adulthood


Correct Option: B

Which transgenic animal have been given human genes for organ transplantation into human without risk of rejection

  1. Cow

  2. Sheep

  3. Goat

  4. Pig


Correct Option: D

What is true among the following w.r.t transgenic cows? 

  1. The milk had a protein called human $\alpha - lactalbumin $

  2. The 1st transgenic cow was called Rosie

  3. Both A and B are correct

  4. None of these


Correct Option: C
Explanation:
The first transgenic cow was Rosie and was produced in 1997. It carried the gene for human alpha-lactalbumin.

So, the correct answer is 'Both A and B are correct'.

"Ethical Sequence" refers to a philosophy:

  1. Limitation on freedom of speech

  2. Limitation on freedom of action

  3. Limitation on freedom of benefits

  4. Limitation on freedom of interest deduction


Correct Option: B

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
