A Gene That Codes for a Protein Was Removed from a Eukaryotic

A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed, the protein translated from this transcript was different from the protein produced in the eukaryotic cell. What is the most likely explanation?

A) There are slight differences in the genetic code for prokaryotes and eukaryotes.
B) Unlike eukaryotes, which have three different RNA polymerases, prokaryotes have a single RNA polymerase.
C) Eukaryotic genes often contain introns while prokaryotic genes do not.
D) Eukaryotic transcripts have a 5' cap while prokaryotic transcripts do not.
