The statement 'DNA nucleotides contain a different sugar than RNA nucleotide' BEST summarizes the structural differences between DNA and RNA (Option C).

DNA is a double helix molecule composed of two long chains of nucleotides that are paired by hydrogen bonds, whereas RNA molecule is a single strand of nucleotides.

In DNA, each nucleotide is composed of a deoxyribose sugar, a phosphate group and a nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

In the single-stranded RNA molecule, each nucleotide contains ribose sugar instead of deoxyribose.

Moreover, in RNA, Uracil bases replace Thymine bases.

In conclusion, the statement 'DNA nucleotides contain a different sugar than RNA nucleotide' BEST summarizes the structural differences between DNA and RNA (Option C).
