Eukaryotic and prokaryotic organisms differ in how they process genetic information. Which statements best explain one of these differences?
A. In prokaryotes, translation occurs before genes are transcribed into mRNA. In eukaryotes, genes are transcribed into mRNA that is then translated into polypeptides. B. In prokaryotes, introns are removed before genes are transcribed into mRNA. In eukaryotes, introns are removed after genes are transcribed into mRNA. C.
