Answer 2

Answer:

b) phosphodiester bonds

Explanation:

Nucleotides are linked together to form polynucleotide chains. They are joined to one another by covalent bonds between the phosphate of one and the sugar of another. These linkages are called phosphodiester bonds. Phosphodiester bonds form the sugar-phosphate backbone of both DNA and RNA.
