How are nucleotides structured, and which bonds connect the sugar to the phosphate and the bases to the sugar?

Explanation:
Nucleotides have a sugar, a phosphate, and a base. The sugar-phosphate backbone is built by phosphodiester bonds, which link the phosphate of one nucleotide to the sugar of the next nucleotide, forming the repeating sugar–phosphate chain. The base is attached to the sugar through a glycosidic bond (an N-glycosidic linkage between the sugar’s 1' carbon and the base). So, phosphodiester bonds connect sugar to phosphate, and glycosidic bonds connect sugar to the base. The other bond types mentioned aren’t responsible for forming the nucleotide backbone or the sugar–base connection.
