Gene regulation in eukaryotes is more complicated than bacterial gene regulation.Which of the following describes a gene regulation event that occurs in eukaryotes but not in bacteria?

A)In eukaryotes,mRNA does not need to be modified.
B)In eukaryotes,histones must be added or removed to regulate gene expression.
C)In eukaryotes,transcription and translation occur in the same cellular compartment.
D)In eukaryotes,proteins are post- translationally modified,whereas bacterial proteins are never post- translationally modified.
E)In eukaryotes,mRNA degrades quickly compared to bacterial mRNA that is more stable.
