Question

Hydrogen bonds are found in all of the following EXCEPT

A) between water molecules.
B) between phosphates in ATP.
C) between the R groups of amino acids in proteins.
D) in α-helices.
E) in the DNA double helix between nucleotides.

Answer 1

Hydrogen bonds are found in all of the following except (C) between the R groups of amino acids in proteins.

Step-by-step explanation:

Hydrogen bonds are found in all of the following except (C) between the R groups of amino acids in proteins. Hydrogen bonds are weak interactions between two polar molecules or between partially charged parts of molecules. These bonds are responsible for stabilizing the structures of proteins and DNA, as well as holding together the two nucleotide chains of a DNA molecule and the phosphates in ATP. However, hydrogen bonds do not form between the R groups of amino acids in proteins.
