The correct answer is option D – The DNA molecule will code for a different protein. A change in the DNA molecule will cause a change in the RNA transcription and eventually lead to the formation of a different protein. The effect of this change will depend on the kind of mutation that occurs due to this change. If it is silent mutation, the same amino acid was coded and this will have no change or less effect on the structure and function of the protein.

If the amino acid produced is different from the initial amino acid at the site of the change, a nonsense mutation or missense mutation has occurred. This will affect the function and structure of the protein produced. This mutation also causes premature signals to stop making protein resulting in a shortened protein that will not function properly.

The answer is D.) The DNA molecule will code for a different protein. The severity of the effect will be different depending on the mutation. An example is a missense mutation, it is when the cause of a substitute is a same amino acid. The function and structure of the protein are less severe.

But if the substituted amino acid is different from the original, it can cause a more severe effect on the protein’s function and structure. The effect on the organism of this change in the DNA differs that might have no effect or can be harmful to the organism. But whenever there is a change in the DNA molecule, it will always code for a different protein to sustain the DNA.
