Question: what are the 3 parts of a nucleotide how are they arranged?
Answer: Nucleotides are made up of 3 parts. The first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine. ... The third part of a nucleotide is the pentose (5 carbon) sugar. The pentose sugars found in nucleotides are aldopentoses: ribose in RNA and deoxyribose in DNA.
