Which of the following mutations would you expect to have the greatest effect on a living cell?

Question

A. A mutation that changes a single base in a region of noncoding DNA
B. Energy release from plutonium
C. Consumptions of preexisting organic compounds

Im clueless!!!

Answer 1

I think B. Plutonium is radioactive. A mutation that changes a single base in a region of noncoding DNA would not have any or would have minimum effect on a cell. And most of the stuff that living beings consume are carbon based.
