The building block of DNA is called the nucleotide, which is composed of a nitrogenous base (adenine, guanine, cytosine, or thymine), a five-carbon sugar (deoxyribose in DNA), â¦ and one to three phosphate groups.he phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without  de-  one oxygen  -oxy- . There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine.
