373. What is a promoter site?

a. A start site for DNA replication
b. A start site for DNA transcription
c. The binding site for regulatory proteins that will allow for transcription
d. The site on DNA at which RNA polymerase binds to initiate transcription
e. More than one of these

Answer in back on book
D
The six-protein enzyme complex called RNA polymerase binds to a specific site on the DNA called the promoter site, hence determining where transcription begins. Transcription and translation have several differences in prokaryotes and eukaryotes, but both employ a promoter site to determine where transciption begins

So based on that shouldnt the answer be B and D? The answer mentions clearly that this is where transcription begins...

I would have thought the same.

When they say "Start site," I guess they mean the site where the first nucleotide of RNA is created.

This must be a typo. Your answer should be correct. Have you tried e-mailing Dr. Romano?

 

[LazyP]

could be a typo, but if this question came on the DAT I would pick D because it is a better answer than B

 

[ICUrunning]

alright thanks everyone

 

[SherrifMcLawdog]

The promoter region is not transcribed so B cannot be correct

 

[M2301]

The start site for DNA translation starts at a primer, while the start site for RNA is a promoter

 

[tongyicha]

The start site for DNA translation starts at a primer, while the start site for RNA is a promoter

Destroyer is correct here. You are confusing transcription initiation site with a promoter site. The question is asking for a promoter site. This is a site where RNA polymerase binds before RNA begins to be synthesized ( made). Transcription start site, is the series of nucleotides on the DNA, where RNA begins to be assembled. Hope this helps.

Got it, thanks!!
