Which of the following describes the action of RNA interference (RNAi) in organic chemistry?
A
RNAi leads to the degradation of specific mRNA molecules, preventing protein synthesis.
B
RNAi modifies the structure of DNA, altering genetic information.
C
RNAi enhances the transcription of specific genes, increasing protein production.
D
RNAi facilitates the replication of RNA molecules, increasing their abundance.
Verified step by step guidance1
RNA interference (RNAi) is a biological process used to regulate gene expression. It involves small RNA molecules that bind to specific mRNA sequences, leading to their degradation.
The primary function of RNAi is to prevent the translation of mRNA into proteins, effectively silencing specific genes.
RNAi does not modify the structure of DNA or alter genetic information directly. Its action is post-transcriptional, meaning it affects mRNA after it has been transcribed from DNA.
RNAi does not enhance transcription or increase protein production. Instead, it reduces protein synthesis by targeting mRNA for degradation.
RNAi does not facilitate the replication of RNA molecules. Its role is to decrease the abundance of specific mRNA molecules, thereby reducing the production of corresponding proteins.
