Question

Assertion [A]: DNA/transgenic technology is more advantageous than traditional cross breeding techniques.
Reason [R]: It is difficult to identify precise genes which improve plant quality in traditional breeding techniques.

• A. Both A and R are true and R explains A
• B. Both A and R are true but R does not explain A
• C. A is true and R is false
• D. A is true and R is false

Answer 1

The correct option is A Both A and R are true and R explains A

Transgenic plants can be made by rDNA technology using DNA from different species like viruses, bacteria, other plants and animals. rDNA technology is faster than traditional breeding and enables the gene of interest to be precisely identified and expressed in the transgenic plant. These factors make rDNA /transgenic technology more advantageous as compared to traditional cross breeding.
