What is antisense technology?

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

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

Solution

Antisense technology uses a sequence complementary to a specific mRNA, so it binds to that message and prevents it from being translated into protein. This is a targeted way to silence a gene’s expression.
