B)nuclei
C)cell membranes
D)mRNA molecules

Question

Quizplus · Accepted Answer

The attraction and repulsion of positive and negative charges between amino acid residues in a protein is responsible for the formation of its secondary and tertiary structures. This is because different types of bonds, such as hydrogen bonds, ionic bonds, van der Waals forces, and hydrophobic interactions, form between amino acids based on their charges and polarity. These bonds cause the protein chain to fold into a specific structure that is held in place by its interactions with other parts of the chain.
