Select one:

a. metabolics binding to cis-acting elements

b. repressor proteins binding to operator sites.

c. trans-acting factors binding to cis-acting elements.

d. cis-acting elements that migrate to bind to trans-acting factors.

Answer 1

Question

The promoter region is the DNA region to which RNA polymerase bind and initiate the process of transcription. Hence, option c is correct.

Question

The promoter region is the specific region in the DNA where transcription get started. It is present in both prokaryotes and eukaryotes. Hence, option e is correct.

Question

In eukaryotes, transcription gene control is mediated by trans acting factor bindibg to cis acting elements. Hence, option c is correct.
