Small single-stranded RNA molecules called microRNAs (miRNAs) are capable of base pairing with specific binding sites in the 3′ untranslated region of many mRNA transcripts. Transcription of gene Q yields an mRNA transcript that contains such an miRNA binding site, which can associate with miRNA‑delta, a specific miRNA molecule. Which of the following best supports the claim that binding of miRNA‑delta to the miRNA binding site inhibits translation of gene Q mRNA?When the promoter for gene Q is altered, transcription is inhibited. ATranslation of Q mRNA is inhibited regardless of whether the miRNA binding site sequence is altered. BTranslation of Q mRNA is inhibited in the absence of miRNA‑delta. CWhen the miRNA binding site sequence is altered, translation of Q mRNA occurs in the presence of miRNA-delta. D
