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
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The 'Ethical Sequence' as described by Aldo Leopold refers to the evolution of ethics from individual relations to relations with the community and eventually the land, which implies a limitation on freedom of action in the struggle for existence.

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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 needed for gene transformation and its screening in animals?

  1. Foreign DNA

  2. Plasmid

  3. Selectable marker

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Successful gene transformation requires the foreign DNA itself, a vector (like a plasmid) to carry it, and a selectable marker to identify which cells have successfully taken up the DNA.

Which of the following is more sufferer?

  1. Native animals

  2. Transgenic animals

  3. Both A and B

  4. Hybrid animal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Both native animals and transgenic animals suffer in different ways - native animals from ecological disruption and competition, and transgenic animals from the genetic manipulation procedures and health effects. The question asks which suffers more, and the answer implies both experience significant suffering.
