83. Which of the following statements correctly describes how miRNA degrades target mRNA?
(A) After mature miRNA binds to RISC, it suppresses translation when partially complementary to the mRNA.
(B) miRNA directly binds to the mRNA poly-A tail to promote its degradation.
(C) miRNA functions in the nucleus and promotes mRNA degradation by altering DNA methylation.
(D) miRNA inhibits mRNA transcription by interfering with RNA polymerase II, ultimately leading to mRNA degradation.
(E) Dicer cleaves pri-miRNA in the nucleus, while Drosha processes pre-miRNA in the cytoplasm.
