DNA is often described as looking like a twisted ladder, a shape known as a . It is made up of smaller building blocks called nucleotides , each consisting of three parts:
: Along with the sugar, this forms the "backbone" or the outer sides of the ladder. what does dna stand for
: Connects the phosphate to the chemical bases. DNA is often described as looking like a
: Describes its chemical property as an acidic substance. Chemical Structure: The "Ladder of Life" : Describes its chemical property as an acidic substance

These bases follow strict : A always pairs with T , and C always pairs with G . History and Discovery
: Refers to the sugar component, deoxyribose . It is called "deoxy" because it has one less oxygen molecule than the sugar (ribose) found in RNA.
