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

zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

  1. Microprojectile gun method

  2. Microinjection method

  3. Liposome-mediated gene transfer

  4. None of the above

Show answer
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?

Which of the following is used as probiotic?

zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

  1. Rhizobium

  2. Lactobacillus

  3. E. coli

  4. Streptomyces

Show answer
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."
