Transcription is the transfer of genetic information from DNA to RNA, and it happens in the nucleus. We can automatically rule out B. B is incorrect because it doesn't make sense; how can a process stop before it even begins?
A. I believe this is incorrect because mRNA is involved when the genetic information needs to leave the nucleus. mRNA would take it to a ribosome outside of a nucleus. Since transcription happens in the nucleus, mRNA is irrelevant before it starts.
C. This doesn't really make sense. mRNA carries information from the DNA, but not vice versa (in these early stages).
D. This would make the most sense, since RNA polymerase needs to attach to the promoter on the strand before transcription can begin.

Hello!
The type of polymer that is made by bonding an alkene to one or more alkanes or alkenes is called addition polymer
Addition polymers are those whose polymerization reaction doesn't produce low molecular mass compounds but the bonding of molecules one after the other. Such a reaction implies that there is a rupture in the bonding between monomers (the building blocks of the polymer) to allow the formation of a chain.
Bonding an alkene to one or more alkanes or alkenes is an example of an addition polymerization.
Have a nice day!
