Homework Answers
I believe the correct answer to be:
Option D) RNA polymerase II, III, I.
As The main difference between RNA Polymerase 1, 2 and 3 is that the RNA polymerase 1 (Pol 1) transcribes rRNA genes and, the RNA polymerase 2 (Pol 2) mainly transcribes mRNA genes while the RNA polymerase 3 (Pol 3) mainly transcribes tRNA genes.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Prokaryotic mRNA usually encodes for more than one protein while eukaryotic mRNA a single protein. Eukaryotic DNA is linear and bacterial and archaeal DNA is-linear. In prokaryotes, ribosomes attach to the mRNA and start protein synthesis even before transcription is completed. Eukaryotic mRNA, rRNA, and tRNA are all highway processed. Nuclear pore complexes control the entry and exit to and from the nucleus. They will not let mRNA exit the nucleus before it is full processed. Eukaryotic and archaeal DNA...

Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...
