Test: GRE Subject Test: Biochemistry, Cell, and Molecular Biology
1. | Which of the following descriptions reflects a nonsense mutation? |
A mutation in a gene causes a valine to be replaced by a glutamic acid residue in the final protein product.
A uracil is replaced by an adenine in the primary transcript, resulting in a severely shortened final protein product.
An adenine is improperly added into a gene, resulting in a completely different amino acid sequence downstream to the mutation.
A transition mutation changes one nucleotide in a gene, but the final protein still has the same amino acid structure as it did prior to the mutation.
