Attenuation Regulation in the trp Operon II

CELLS-SJHPTY

The attenuation control system of the trp operon functions in a bacterial cell, E. coli, but a similar system would very likely not function in a eukaryotic cell.

What is the primary reason it would not? In other words, which of the following is unique to a bacterial cell and affects attenuation?​

A

Most bacterial genes do not have introns.

B

The RNA polymerase and ribosomes of bacteria differ from those of eukaryotes.

C

Transcription and translation occur simultaneously in bacterial cells.

D

Eukaryotic cells generally have many chromosomes, while bacterial cells have only one.
