  1. Conversion of perishable raw material into the nonperishable food product

  2. Conversion of nonperishable raw material into food product

  3. Conversion of decayed food into useful food products

  4. None of these

Show answer
Correct Option: A
Explanation:

Answer is option A i.e. "Conversion of perishable raw material into the nonperishable food product"
Biotechnology in the food processing sector makes use of micro-organisms for the preservation of food. Food processing is a process by which perishable raw materials are converted to edible and  non-perishable foods and beverages, which have a longer shelf life.

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

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

  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

Show answer
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'.
