Which of the following statements about the interaction between nucleic acids and proteins is incorrect?

AThe major groove of DNA double helix can accommodate protein alpha-helices
BDNA bases and pentose sugars can form hydrophobic interactions with proteins
CDNA phosphate groups can form ionic bonds with protein side chain -NH3+
DDNA bases cannot form hydrogen bonds with proteins

Correct answer: D. DNA bases cannot form hydrogen bonds with proteins

Nucleic acids, such as DNA, can indeed interact with proteins through various mechanisms. The major groove of DNA can accommodate alpha-helices, DNA bases and pentose sugars can engage in hydrophobic interactions, and phosphate groups can form ionic bonds with protein side chains. However, nucleic acid bases do have the ability to form hydrogen bonds with proteins under certain conditions.
