How does a mutation in the DNA affect the way proteins are made?
A. A mutation in the DNA results in misshapen tRNA molecules that do not fit inside the ribosomes.
B. A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.
C. A mutation in the DNA affects the structure of mRNA, but it does affect the protein.
D. A mutation in the DNA changes how the proteins that are made are passed down from parent to child.
Is the answer D?
Thanks a bunches ;)
no the answer is really B OK
Yeah, the answer is B, I just took the test.
please im begging you.
No, the correct answer is B. A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.
When a mutation occurs in the DNA sequence, it can lead to changes in the corresponding mRNA molecule during transcription. This altered mRNA molecule may then carry a different genetic code, leading to changes in the sequence of amino acids during translation. As a result, the protein that is ultimately synthesized may have a different structure and function compared to the original protein.
To arrive at this answer, you can eliminate options A and D because they do not accurately explain how mutations affect protein synthesis. Option C is also incorrect since a mutation in the DNA can indeed affect the ultimate protein structure. Therefore, B is the correct choice, as it accurately describes how mutations in DNA affect the production of proteins.
