What happens right before transcription begins?
Ahat [919]
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.

D. descriptive investigations

Explanation:

A scientist studying the star Alpha Centauri would probably rely on descriptive investigation to gather data.

In descriptive investigation, experiments cannot be performed since the subjects cannot easily be manipulated or they are far too inaccessible. This form of investigation is based on indirect qualitative investigation of a phenomenon.

  • Alpha Centauri is a distant star several light years away from the vicinity of the scientist.
  • The best way to investigate this distance body is to make inferences from the evidence gathered from observatory stations using telescopes.
  • Astronomers can collect different information and give vivid description of the distant start.
  • It is highly impossible to make comparisons and alter variable in this kind of investigation.
