Question

What is antisense technology?

• A. When a piece of RNA that is complementary in sequence is used to stop expression of a specific gene
• B. RNA polymerase producing DNA
• C. A cell displaying a foreign antigen used for synthesis of antigens
• D. Production of somaclonal variants in tissue cultures

Answer 1

Answer: (A)

When a piece of RNA that is complementary in sequence is used to stop expression of a specific gene

Antisense technology is a tool that is used for the Inhibition of gene expression. Antisense technology using antisense RNA and small interfering RNA, which inhibit the expression of a target gene. Thus, the option is A: When a piece of RNA (antisense RNA) is complementary in the sequence is used to stop expression of a targetted gene.

It can also be used to downregulate enzymes controlling undesirable pathways. Antisense technology is supposed to prevent protein production from a targeted gene.
