Which condition enhances mRNA stability using AU-rich elements?

A)Deadenylation via accelerated mRNA decay
B)ARE-BP binding inhibits mRNA turnover
C)Exosome degradation after primary cleavage
D)Upstream ORF translation increases destabilization

💡 Explanation

ARE-BP binding inhibits mRNA turnover because AU-rich elements interacting with ARE-binding proteins block mRNA degradation pathways using the mechanism of steric hindrance; therefore stability increases, rather than decreasing it as exosome activity would.
