Attenuation of gene expression is unique to prokaryotes,because it requires translation of a leader sequence at the same time transcription is taking place.

Question

Quizplus · Accepted Answer

Attenuation is a regulatory mechanism of gene expression that occurs in prokaryotes. It involves the premature termination of transcription before the full gene is transcribed, based on the secondary structure of the mRNA. This structure is determined by the translation of a leader sequence, which occurs simultaneously with transcription. Attenuation is not observed in eukaryotes, as they do not have a similar mechanism of coordinating transcription and translation.
