Q. What is antisense technology?
A) RNA polymerase producing DNA
B) A cell displaying a foreign antigen used for synthesis of antigens
C) Production of somaclonal variants in tissue cultures
D) When a piece of RNA that is complementary in sequence is used to stop expression of a specific gene
Explanation
[Solution from source] Antisense technology uses an RNA (or DNA) strand complementary to a target mRNA. It pairs with the mRNA and blocks its translation, silencing the gene, the same principle as RNA interference in NCERT. Making DNA from RNA is reverse transcription, not antisense technology.
