Question

Which of the following products are obtained with help of biotechnology?
A. Transgenic Crop
B. Biofertilizer
C. Humulin
D. All of the above

Answer 1

As we knew that GMO or genetically modified crops are crops which are artificially made. The DNA of the crops or plants which are modified by using genetic engineering methods or techniques are a sub-type of field biotechnology. Plant genomes can be modified physically or via Agrobacterium to produce sequences hosted by T-DNA vectors.

Complete answer:
Option A: Transgenic Crop- Transgenic crops are nothing but modified GMO crops. In India, genetically modified BT brinjal (BT stands for Bacillus thuringiensis) has been produced primarily for insect or pest resistance. BT toxin genes were extracted from Bacillus thuringiensis and integrated or inserted into numerous crop plants by genetic engineering.
Option A is not the correct answer.
Option B: Biofertilizer- Biofertilizers are also modified from a biotechnology aspect. Normal fertilizers are not cost effective and biofertilizers are cost effective, disease free.
Option B is not the correct answer.
Option C: Humulin- Humulin is also known as- bio-insulin. Humulin is a cultured insulin. Unlike- normal insulin extracted from human liver cells. Humulin is cultured in lab conditions.
Option C is not the correct answer.
Option D All of the above- this option is correct as all of the above options are absolutely correct.
Option D is the correct answer.

Therefore, Option D is the correct answer.

Note:
The Effectiveness of the crop against pests is quite satisfactory. The larvae of the insect feed on the BT brinjal plant, they ingest the BT protein $CryA1C$ along the plant tissue. In the insect gut which is alkaline in nature is activated by the gut proteases. The protein binds to specific receptor proteins found in the insect membrane, causing pores in the stomach to form, causing digestion paralysis to be disrupted and the larvae to die.
