Which type of chemical bond attaches deoxyribose molecules together to form the backbone of a DNA molecule?

Question

Quizplus · Accepted Answer

The backbone of DNA is formed by phosphodiester bonds, which connect the 5' carbon of one deoxyribose molecule to the 3' carbon of another via a phosphate group. These bonds are covalent in nature, meaning they involve the sharing of electrons between atoms. Hydrogen bonds do play a role in stabilizing the double helix structure of DNA, but they specifically form between the nitrogenous bases and not the deoxyribose molecules themselves. Peptide bonds form between amino acids in proteins, and ionic bonds involve the transfer of electrons between ions with opposite charges.
