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.
As the story goes, after thoroughly enjoying his joe, Teddy smacked his lips and declared that the stuff was âgood to the last drop.â Some years later, the coffee giant decided the slogan was a double win - it was a catchy phrase, but it also provided celebrity endorsement.
