Where are hydrogen bonds in proteins?

• Between amino acids in the primary structure

• Between the backbone in the secondary structure

• Between the R groups in the tertiary structure

• Between polypeptides in the quaternary structure

Where are hydrogen bonds in nucleic acids?

• Between carbons in the sugar ring

• Between nitrogenous bases

• Between nucleotides

• Between phosphates

Answer explanation

Hydrogen bonds hold the two strands of DNA together.

A macromolecule is found to have the elements C, H, O, N, & S - Identify.

• Carbohydrate

• Lipid

• Nucleic Acid

• Protein

Answer explanation

Not ALL proteins have sulfur - only a couple of amino acids contain this element.
