➠Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins.

•Promoter sequences are typically located directly upstream or at the 5' end of the transcription initiation site.

➠Effervescence is defined as the rapid or vigorous evolution of a gas in a chemical reaction.

•For example, when hydrochloric acid is added to sodium bicarbonate, bubbles of carbon dioxide gas are formed vigorously.
