|The diagram shows part of a DNA molecule. DNA is a polymer. What is the evidence from the diagram that DNA is a polymer?

DNA is a polymer due to the fact it contains multiple repeating units (monomers). These monomers are known as nucleotides. Multiple nucleotides join together by phosphodiester bonds to form the polymer that is DNA.
Nucleotides are made from 3 components. A 5 carbon Ribose sugar, 1 of 4 nitrogenous organic bases (A, T, G and C) and a phosphate group.
