Exam 15: Eukaryotic and Archaeal Genome Replication and Expression

Most archaeal mRNAs like those of eukaryotes are spliced.

Enhancer sequences for transcription activation in eukaryotes can exert effects from a great distance of the transcription target by forming loops or changing DNA structural elements.
