Hello I am doing a few practice problems for an upcoming exam and would appreciate the help! 5.

Promoters are key elements required for transcription. Which of the following statements are true regarding promoter regions? Choose all that are true.

A) A TATA box upstream of the transcriptional start site is recognized by transcriptional machinery in eukaryotic cells

B) Promoter regions, and hence the beginning of transcription, are designated by the ATG codon at the start of a gene.

C) The -10 and -35 boxes upstream of the transcriptional start site is recognized by the sigma70 subunit in prokaryotic cells

D) Mutations in the promoter region can reduce the binding of transcriptional machinery and affect the amount of transcripts that are generated from a gene

I chose A, B, and C. Is this correct?
