Hydrogen bonding between different parts of large molecules like proteins and DNA helps determine the molecule's three-dimensional shape.

Question

Quizplus · Accepted Answer

Hydrogen bonding plays a crucial role in determining the three-dimensional structure of large molecules like proteins and DNA. These bonds occur between different parts of the molecule, such as amino acid side chains in proteins or nucleotide bases in DNA, and help stabilize the overall shape of the molecule. Without hydrogen bonding, these molecules would not be able to fold into their functional shapes, and their biological activities would be compromised.
