With respect to how miRNAs work, which, if any, of the following statements, is false?
A) An miRNA is initially composed of two RNA strands, a passenger strand that will be destroyed and a complementary RNA, the guide strand, that is required for it to work.
B) an active miRNA regulates target protein-coding genes by binding to complementary sequences in the mRNA
C) A single miRNA normally binds to transcripts from just one target gene
D) A single type of mRNA can be regulated by multiple different miRNAs.

Question

Quizplus · Accepted Answer

MiRNAs can bind to transcripts from multiple different target genes, not just one. This allows a single miRNA to regulate a broad range of biological processes by targeting multiple mRNAs that may be involved in similar or interconnected pathways.
