Prokaryotic and Eukaryotic RNA's Differ in That

Question

Prokaryotic and Eukaryotic RNA's differ in that:
A) rRNA molecules are only subunits of the prokaryotic ribosome.
B) Eukaryotes have a pre-mRNA that requires splicing to create the functional transcript
C) Prokaryotes have non-coding sequences that are removed during RNA-transcript processing
D) Eukaryotes have simpler ribosomes, consisting of fewer subunits.
E) None of these

Accepted Answer

Eukaryotes have a pre-mRNA that requires splicing of introns to create the functional mRNA transcript. Prokaryotes do not have introns and their mRNA is transcribed directly into a functional transcript without splicing. The statements in options A, C, and D are not true for all prokaryotic and eukaryotic RNA molecules.
