Transcription of DNA Promoter site A specific base sequence found within a DNA chain typically consisting of around 40 base pairs located upstream(5)of the transcription start site Consists of two hexameric consensus sequences,one located 10 base pairs upstream and the second located 35 base pairs upstream from the beginning of the coding region Signals the beginning of a gene Other base sequences signal a stop near the end of the gene Promoter site ▪ A specific base sequence found within a DNA chain typically consisting of around 40 base pairs located upstream (5′) of the transcription start site ▪ Consists of two hexameric consensus sequences, one located 10 base pairs upstream and the second located 35 base pairs upstream from the beginning of the coding region ▪ Signals the beginning of a gene ▪ Other base sequences signal a stop near the end of the gene Transcription of DNA
