Question

F) The transcription initiation site is located (3 pts)

i) within the promoter.

ii) on RNA polymerase.

iii) at splice sites.

iv) in a ribosome.

v) all of the above

Answer 1

RN polymerase is the enzyme that transcribes the DNA into RNA, ribosomes consist of RNA and protein and it translates mRNA into protein.

the RNA usually have exons at both ends and introns are placed in between the exons, splice sites are found at the ends of the introns, so the transcription start site is not located at splice sites.

the promoter is the region where RNA polymerase binds and starts the transcription so the answer is i) within the promoter.
