Select all that apply. How is transcription of RNA different between Archaea and Bacteria?
The coding strand is transcribed in Archaea while the template strand is transcribed in Bacteria.
mRNA contains introns in Archaea but not in Bacteria.
RNA polymerase is similar between Archaea and Eukarya; it is different in Bacteria.
The consensus sequences of promoters are different in Archaea and Bacteria.
Bacteria habe -factors; Archaea have general transcription factors like Eukarya.
Only constitutive gene expression is possible in Archaea; Bacteria also have inducible expression.
RNA synthesis is 5'-to-3' in Archaea and 3'-to-5' in Bacteria.
Only coarse control of protein levels is possible in Bacteria; Archaea also have fine control.
Translation is coupled to transcription in Bacteria but not in Archaea.
Genes are organized into operons in Bacteria but not in Archaea.
