Question

question 26 during protein folding, this stage has charge interactions attracting portions of the polypeptide to itself a. tertiary b. secondary c. primary d. quartenary

Explanation:

Protein folding has four levels. The tertiary structure involves charge - charge interactions, hydrophobic interactions, and hydrogen bonds that cause different parts of the polypeptide chain to interact with itself, leading to the overall 3 - D shape of a single polypeptide. The secondary structure is mainly about local regular structures like alpha - helices and beta - sheets formed by hydrogen bonds between backbone atoms. The primary structure is just the linear sequence of amino acids. The quaternary structure involves the interaction between multiple polypeptide chains.

Answer:

A. tertiary
