Question

Statement I: Specific RNAi sequences are introduced into the cell which binds to and destroys its mRNA target.

Statement II: RNAi molecules can either increase or decrease a gene’s activity.

• A. Only statement I is correct
• B. Only statement II is correct
• C. Both statements are correct
• D. Both statements are incorrect

Answer 1

The correct option is C Both statements are correct

RNA interference (RNAi) is a process in which RNAi molecules are used to inhibit gene expression. Specific RNAi sequences are introduced into the cell which binds to and destroys its mRNA target. RNAi molecules can either increase or decrease a gene’s activity by preventing an mRNA from producing a protein or by blocking an expression inhibitor therby increasing the gene's activity.
