B) exons
C) polycistrons
D) introns

Question

Quizplus · Accepted Answer

Introns are non-coding regions of mRNA that are often removed by splicing before translation. The coding regions, or exons, are typically left intact. Poly(A) tails are added to the 3' end of mRNA and aid in stability and recognition by translation machinery. Polycistrons are found in prokaryotic mRNA and contain multiple coding regions for different genes.
