What is a promoter? it's a region of dna that binds dna polymerase to begin replication. it's a protein that promotes transcription it's a region of rna that binds ribosome to begin protein synthesis. it's a region of dna that binds rna polymerase to begin transcription?

Protein and polypeptide sequences can be determined by first partially hydrolyzing the protein or polypeptide followed by amino acid sequencing of the fragment pieces using the chemical degradation process known as edman degradation. determine the sequence of the initial (18-amino acid) polypeptide that produces the following five partial sequences after hydrolysis and edman degradation.
