Revision Questions: Biotechnology Applications

The questions that follow are strictly based on NCERT class 12 Lesson 12: Biotechnology & Its applications
The aim of these questions to make the student familiar with the concepts presented in the book, to enable the students to grasp the concepts and to help them solve higher level questions at a later stage.
However, it is very important that the questions are solved by the students only with the help of NCERT book and not with the help of Internet. 
Primary goal is to help in reading and understanding the lesson through reading text.
So here goes:


QUESTIONS:
  1. 3 Critical areas & 4 fields of applications of Biotechnology
  2. 5 advantages of GMO
  3. Draw flow charts to elucidate:
  • Mode of production & activation of toxins produced by Bacillus thuringiensis
  • Mechanism of control of Meloidogyne by RNAi  
  • Production of Human Insulin by Eli Lily
  • Method of treatment of ADA Deficiency
Biotechnology In Agriculture

  1. Which groups of insects are vulnerable to crystals of Proteins of Bacillus thuringiensis?
  2. Does Bacillus thuringiensis produces toxic proteins at all stages of its life cycle? Why is the bacteria itself not vulnerable to the toxic present in its protein crystals?
  3. How is activity of protoxin different from that of toxin present in Bacillus thuringiensis protein crystals.
  4. How will your choice of cry gene for producing insect resistant crop vary if you are growing:
  • Cotton
  • Corn
Why does your choice vary?
  1. What is Meloidogyne incognita? what is its significance?
  2. What are transposons? How are they involved in RNA interference?
  3. When does RNAi occur naturally in an organism?
  4. which other agents, besides Transposons, are involved in RNAi?
