A nucleotide is composed of a _____ bonded to both a _____ _____ and a _____ _____.

Explanation:
A nucleotide is built from a five-carbon sugar that holds a phosphate group on one side and a nitrogenous base on the other. The sugar acts as the central scaffold; the phosphate group links nucleotides together to form the backbone via phosphodiester bonds, while the attached nitrogenous base provides the genetic information through base pairing with another strand. The other options introduce components that aren’t part of a nucleotide (lipids, proteins, carbohydrates), and using a “base pair” describes interactions between two nucleotides, not a single nucleotide’s structure.
