Many pharmaceutical drugs specifically inhibit transcription in Bacteria but not Archaea or Eukarya. Why would drugs that inhibit transcription only affect Bacteria and not Archaea even though they are both prokaryotes?
A) Archaea and Eukarya have very similar ribosomes that are different than bacterial ribosomes.
B) Bacteria lack a nucleus.
C) Archaea lack operons.
D) Archaea and Eukarya have very similar RNA polymerases that are different than bacterial RNA polymerases.

Archaea and Eukarya share a more similar RNA polymerase structure, which is significantly different from that of Bacteria. This difference allows for the development of drugs that specifically target the bacterial RNA polymerase without affecting the RNA polymerase in Archaea and Eukarya.
