Question

Quizplus · Accepted Answer

Shine-Delgarno sequences are present in the mRNAs of prokaryotes, specifically in the 5' untranslated region (UTR). They are essential for translation initiation in prokaryotic cells by providing a ribosome binding site. Eukaryotic cells do not have Shine-Delgarno sequences; instead, they use different mechanisms of translation initiation. Thus, choices B-E are incorrect.
