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 his booth, Clark thrust a cup of his coffee at himâa cup the president promptly drained in a gulp. Setting down the empty cup, Roosevelt turned to the people around him and declared the coffee good to the last drop, thus giving Clark and his brand of coffeeâMaxwell Houseâa slogan that lives to this day.
