Below is a list of mutations made within a protein. For each,
explain in energetic and/or structural terms the likely effect of
this mutation on the structure and stability of the protein.
(please give clear explanations

a. Mutation of a phenylalanine in the protein interior to a
lysine residue.

b. Mutation of a glutamic acid on the protein surface to an
isoleucine.

c. Mutation of an arginine in a salt-bridge to a glutamic
acid.

d. Mutation of a serine on the protein surface to a threonine.
e. Mutation of a glycine residue in a loop to a proline. f.
Mutation of surface arginine and lysine residues to alanine in a
DNA-binding protein
