Which is NOT true about point mutation?
I have no clue what the last two people are thinking. All point mutations require the pairing of a non-complementary nucleotide. The genetic code is degenerate. Meaning, nearly every amino acid is coded for by more than one codon. This means that a point mutation may not cause a change in the coded amino acid. Also, point mutations have NO EFFECT on the subsequent codons (unless they are nonsense mutations that end translation). Therefore, the answer to your question is B. It is utterly untrue.
