Question

Which of the following would most likely cause a mutation withthe greatest deletrious effect? A. An insertion of a nucleotide triplet into a DNA strand thatcodes for an mRNA B. A deletion of a nucleotide triplet from a DNA strand thatcodes for an mRNA C. A single substitution of a nucleotide in a DNA strand that,when transcribed, results in a change in the nucleotide occupyingthe third codon position in an mRNA D. A single substitution of a nucleotide in a DNA strand,that, when transcribed, results in a change in the nucleotideoccupying the first codon position in an mRNA E. A single addition of a nucleotide in a DNA strand thatcodes for an mRNA Please explain the answer and pick a choice. Thank You!

Explanation / Answer

The answer is E A single addition of a nucleotidein a DNA strand that codes for an mRNA. This creates a frameshiftmutation. Therefore, the 1st nucleotide in every codon will becomethe 2nd, the 2nd will be the 3rd and so on.It changesthe amino acids in the sequence which in turn, affects theconcluding sequence of the polypeptide.
