The Correct Option is B

Solution and Explanation

RNAi is a regulatory mechanism for an estimated 30% of all protein-coding genes(in mammals). It helps to protect cells against certain viruses by targeting viral RNA for destruction. It helps to silence potentially disruptive transposons in the genome by destroying RNA copies arising from transposon replication. RNAi is a precise and efficient tool for knockout of specific genes when studying gene function in experimental organisms. It also has potential for new forms of targeted gene therapy.

Concepts Used:

Applications of Biotechnology

Biotechnology is the technology that utilizes biological systems, living organisms, or parts of this to develop or create different products.

For example, brewing and baking bread fall within the concept of biotechnology (use of yeast (= living organism) to produce the desired product).

Agriculture

Alternative to conventional farming: A possible solution is the use of genetically modified crops which is an alternative path to conventional farming.

Medicine

In the area of healthcare, recombinant DNA technological processes have made an immense impact which enables the mass production of safe and more effective therapeutic drugs.

Gene Therapy

A collection of methods that allows the correction of a gene defect that has been diagnosed in a child/embryo is called Gene Therapy.

CRISPR technology

For editing genomes, CRISPR is a simple yet powerful tool which allows researchers to easily alter DNA sequences and modify gene function.
