Question

Quizplus · Accepted Answer

Hydrogen bonds can form between amino acid side chains and different regions of the peptide backbone in proteins, contributing to secondary and tertiary structures. They also occur between complementary bases of DNA strands, stabilizing the double helix. However, they do not typically form between phosphate groups in DNA or between different regions of RNA, where they are crucial for secondary structure formation.
