Question

which of the following best predicts how the amino acid deletion will affect the structure of the cftr protein? a it will have no observable effect on the structure of the cftr protein. b it will affect the primary structure of the cftr protein, but the other levels of protein structure will not be affected. c it will affect the secondary and tertiary structures of the cftr protein, but the primary structure will not be affected. d it will affect the primary, secondary, and tertiary structures of the cftr protein.

Explanation:

The primary structure of a protein is the linear sequence of amino - acids. Amino - acid deletion changes this sequence. Since secondary and tertiary structures are formed based on the primary structure (hydrogen bonds, hydrophobic interactions etc. that depend on the amino - acid sequence), a change in the primary structure will affect the secondary and tertiary structures as well.

Answer:

D. It will affect the primary, secondary, and tertiary structures of the CFTR protein.
