MCAT Question A Day - 5/16/14 - Answer!

One difference between prokaryotic and eukaryotic translation is:

A.  eukaryotic ribosomes are larger containing more subunits.
B.  prokaryotic translation may occur simultaneously with transcription while eukaryotic translation cannot.
C.  prokaryotes don't contain supra molecular complexes such as ribosomes.
D.  prokaryotic DNA is circular so does not require a termination sequence.

B is correct. Only choice B is both true and concerns translation. Ribosomes contain two subunits for both eukaryotes and prokaryotes, so choice A is incorrect. Prokaryotes do contain ribosomes, so choice C is wrong. Translation does not concern DNA, so choice D is incorrect.
