Answer:
e. unique three-dimensional shape of the fully folded polypeptide.
Explanation:
The tertiary structure of a protein is the unique three-dimensional structure which emanates from the interaction between the “R groups” of the several amino acids that make up the polypeptide. Hydrogen bonding is one of the interactions that occur that gives the protein this structure. Other interactions are ionic bonding, dipole-dipole interactions, hydrophobic interactions, among others. The function of a protein is dependent on its tertiary structure, as a disruption of the tertiary structure causes a protein to be denatured, thereby rendering the protein not functional.
DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.
