Compared with mRNAs that have a cap and tail, what do researchers observe when eukaryotic mRNAs that lack a cap and poly(A) tail are translated within a cell?
A) The primary transcript cannot be processed properly.
B) Translation occurs inefficiently.
C) Enzymes on the ribosome add back a cap and poly(A) tail.
D) tRNAs become resistant to degradation (being broken down).
