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.

Which of the following is used as probiotic?

  1. Rhizobium

  2. Lactobacillus

  3. E. coli

  4. Streptomyces

B Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.
