what is a promoter? a.)binding site for DNA polymerase. b.) binding site for RNA polymerase. c.)a start signal for replication d.)stop signal for transcription

C. A start signal for replication

In genetics, a promoter is a sequence of DNA to which proteins bind to initiate transcription of a single RNA transcript from the DNA downstream of the promoter. The RNA transcript may encode a protein, or can have a function in and of itself, such as tRNA or rRNA.

Ithink the dna sequences may vary but the amino acid sequences are identical.
