B) No,mutations occurring within the noncoding regions of the DNA sequence will not affect overall protein structure.
C) No,DNA repair enzymes are designed specifically to "proofread" the DNA and they catch most mistakes.
D) Yes,any mutations located within the DNA sequence will affect the structure of the protein.
