Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

A polypeptide only becomes a functioning protein after it has folded into its exact 3D shape.
makkiz [27]
True. A protein becomes functional only when it reaches its tertiary shape (3D). It is not necessary for the protein to reach the quaternary stage, but that is just a more complex functioning protein. It really is just two tertiary merged together. Example is red blood cells.
