Question

What type of bond binds nucleotides together?

Answer 1

Nucleotides are linked together by **phosphodiester bonds**. This type of bond forms between the phosphate group of one nucleotide and the hydroxyl group on the sugar of another nucleotide, creating a backbone for nucleic acids like DNA and RNA. Specifically, the bond occurs between the 5' carbon of one nucleotide's sugar and the 3' carbon of the adjacent nucleotide's sugar, facilitating the formation of a long chain of nucleotides.
