Question

Which of the following is true of transcription in domain Archaea?

A. It involves promoters are identical to those in domain Eukarya.
B. There is only one kind of RNA polymerase.
C. It produces RNA transcripts that are processed after they leave the nucleus.
D. It terminates in a manner similar to that in bacteria.
E. It is regulated in the same way as in domain Bacteria.

Answer 1

Transcription in domain Archaea has different characteristics compared to domain Eukarya and Bacteria. The RNA polymerases, promoters, and termination mechanisms in Archaea are not the same as in Bacteria or Eukarya. Transcription in Archaea terminates in a manner similar to that in bacteria.

Step-by-step explanation:

Transcription in domain Archaea has a few key characteristics. Firstly, option A is not true because the promoters in Archaea are not identical to those in domain Eukarya, but they are more similar to eukaryotic promoters compared to bacterial promoters. Secondly, option B is not true because there is not just one kind of RNA polymerase in Archaea, but rather multiple types. Next, option C is not true because RNA transcripts in Archaea are not processed after they leave the nucleus, since Archaea lack a membrane-bound nucleus. Finally, option E is not true because transcription in Archaea is not regulated in the same way as in domain Bacteria. Therefore, the correct answer is option D, which states that transcription in Archaea terminates in a manner similar to that in bacteria.
