Answer:
RNA polymerase binds to the promoter
Polymerase initiates RNA synthesis at the start point on the template strand
RNA polymerase moves downstream unwinding the DNA
RNA transcript is released and polymerase detaches from the DNA
The pre-RNA undergoes processing
Explanation:
The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.
The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.
In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.
I believe A) would be the most correct answer in this case. However, the most significant difference between eukaryotes and prokaryotes is that eukaryotic cells contain a nucleus, while the latter does NOT.
B) is incorrect because prokaryotic cells are typically smaller than eukaryotic cells. Think bacteria and other microorganisms.
C) is incorrect because, well, energy is…
D) False, a non-living microorganism would be considered a prion or virus before prokaryote.
E) Many prokaryotic cells actually contain flagellum or cilia for transport.
Let me know if you have other questions — good luck.
