U937d cells express high levels of creatine kinase (ck‑b) mrna but do not translate the mrna into protein. ribosomes bind the 5' end of the ck‑b mrna; however, translation into protein is repressed in these cells. u937d cells synthesize the ck‑b enzyme when researchers introduce numerous short segments of rna containing 3' utr consensus sequences into the cells. the total amount of ck‑b mrna does not change after adding rna containing 3' utr sequences. introducing short rna segments without the 3' utr consensus sequences does not stimulate ck‑b synthesis. which of the statements explains how the introduction of short rna containing 3' utr sequences allows ck‑b translation in u937d cells? .explain how the introduction of short segments of rna containing the 3'utr sequences might remove the inhibition.
