Answer:
A genetic sequence, the TATA box, is a transcriptions start site and initiates transcription through the formation of RNA polymerase. Negative regulation may inhibit the initiation of transcription and/or repress gene expression.
Explanation:
proteins called transcription factors bind to the TATA box, this triggers RNA polymerase to start synthesizing RNA to DNA
