You are studying the nucleotide sequences of two strands of DNA: one mutated, one normal. You notice that one area of the mutated gene reads “ACG GGT” while the normal one reads “ATG GCA”. What effect will this difference have on the gene? Select one: The mutated gene will be unstable and break apart in the nucleus. The mutated gene will code for a different protein. The mutated gene will no longer have a double-helix shape. There will be no effect on the structure or function of the mutated DNA.
