It has its own promoter (PI). A gene cluster, including promoter and any regulatory DNA sequences is called an operon, for example, the Lac operon. In this case, transcription from the operon is induced in response to a molecular signal-i.e. the presence of lactose, or allolactose.
Maxwell House Coffee's successful slogan, Good to the last drop was historically credited to the 26th President of the United States, Theodore Roosevelt. The folklore claims that during Roosevelt's visit in Nashville in 1907, he was served Maxwell House coffee. So impressed with the coffee, the president apparently said the famous words.
When Roosevelt walked by the Maxwell House booth, Joel Cheek thrust a cup of his coffee at the President â who promptly drained it in one gulp. Setting down the empty cup, Roosevelt turned to the people around him and declared that this coffee was âgood to the last dropâ â thus giving Maxwell House Coffee this 99-year-old advertising slogan, that helps sell it to this day.
