Deoxyribose sugar and bases in DNA are joined through
Answer: C
Deoxyribose and the bases are joined by a Glycosidic bond.
In each nucleotide of DNA, the nitrogenous base is attached to carbon 1 of the deoxyribose sugar by an N-glycosidic bond, forming a nucleoside. A phosphate group then links to carbon 5 of the sugar.
Phosphodiester bonds join the sugar of one nucleotide to the phosphate of the next, forming the sugar-phosphate backbone, not sugar to base. The two strands are held together by hydrogen bonds between bases, and peptide bonds join amino acids in proteins.
