Which of the following statements concerning translational repression from miRNAs are false? miRNA complexes can cause ribosomes to fall off mRNA prematurely. The removal of the polyA tail by miRNA complexes causes the mRNA to be digested by RiSC. The RiSC complex, when directed my miRNAs, can cause mRNA to become circular in structure which inhibits translation. miRNA directed RiSC complexes can bind to ribosomal subunits preventing the assembly of a functional ribosome (with large and ...
