Question

proteins are made of chains of amino acids, and their specific sequence determines how they fold into a three - dimensional shape. the shape of a protein is directly related to its function in the cell. dna contains instructions for the order of amino acids through a series of three - base codes called codons. a change in even one base of dna can sometimes change the amino acid that is added to the protein. this can result in a slightly different protein shape, which may work less effectively or, in some cases, not at all. however, some changes have little or no effect if the new amino acid is chemically similar to the original. question: a mutation changes the dna triplet gaa to gac. the amino acid glutamic acid is replaced by aspartic acid. what is the most likely effect? (2 points) the protein will have no change in structure or function the protein may fold differently and have reduced or altered function. the mutation will completely stop protein production. the mutation will reverse translation.

Explanation:

The text states that a change in DNA can change the amino - acid added to a protein, which can result in a different protein shape and potentially altered function. Glutamic acid and aspartic acid are different amino acids. So, a change from one to the other is likely to affect the protein's folding and function.

Answer:

The protein may fold differently and have reduced or altered function.
