What is the term for the DNA sequence where RNA polymerase binds to begin transcription?

Explanation:
Promoter sequences are the DNA regions where RNA polymerase binds to start transcription. This region lies upstream of the gene and positions the polymerase so transcription begins at the correct start site. In bacteria, promoter elements such as the -35 and -10 boxes help RNA polymerase–sigma factor recognize the site; in eukaryotes, promoters may include a TATA box and require transcription factors to assemble the initiation complex. The promoter itself is not transcribed. Terminator signals the end of transcription. Codon refers to a three-nucleotide mRNA word that encodes an amino acid during translation. The ribosome is the molecular machine that reads mRNA to synthesize protein, not involved in initiating transcription.
