Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
Answer:
The expression of the mRNA decreases.
Explanation:
The RNAi binds to some proteins forming a silencing complex. This complex binds to the target mRNA (of which the RNAi is complementary) and cleaves it (cuts it). The cell will detect the generated fragments of mRNA , recognize they are aberrant and will thus degrade them.
All in all, this mechanism silences (reduces) the expression of the mRNA, because it will be degraded instead of translated into protein.
