How can artificial antisense genes be constructed?
What will be an ideal response?
Ans: Artificial antisense genes can be constructed by reversing the orientation of a gene with respect to its promoter. This results in transcription of an antisense RNA that is complementary to the mRNA of the original gene, so that they can base-pair and suppress the mRNA's translation or affect its stability.
