A type of chemical compound that is a building block of DNA and RNA, important for storing and transmitting genetic information.
Guanine pairs with cytosine in the structure of DNA.
Guanine is derived from the Spanish word 'guanina', which comes from 'guano' (meaning fertilizer, specifically bird droppings) and the suffix '-ine' (used in chemistry to denote substances). The word guanine refers to a compound found in guano and is one of the four main nucleobases in the nucleic acids DNA and RNA.
Think of 'guano', which is a fertilizer made from bird droppings, to remember that guanine is a substance derived from it and is essential in the structure of DNA and RNA.
