E)a eukaryotic equivalent of prokaryotic promoter functioning.

Question

Quizplus · Accepted Answer

Enhancers are DNA sequences that enhance or increase the transcriptional activity of a promoter. This is an example of transcriptional control of gene expression, as it affects the transcription of the gene into mRNA. Post-transcriptional mechanisms and post-translational control occur after mRNA has been produced and translated into a protein, respectively. The eukaryotic promoter function is similar but not equivalent to the prokaryotic promoter function, as eukaryotes have more complex regulation of gene expression.
