- A gene encodes a protein with the following amino acid sequence: Met-Lys-Ser-Pro-Ala-Thr-Pro A nonsense mutation caused by a single-base-pair substitution occurs in this gene, resulting in a protein with the amino acid sequence Met-Lys. An intergenic suppressor mutation allows the gene to produce the fulllength protein. With the original mutation and the intergenic suppressor present, the gene now produces a protein with the following amino acid sequence: Met-Lys-Cys-Pro-Ala-Thr-Pro Give the location and nature of the original mutation and of the intergenic suppressor.arrow_forwardZidovudine (AZT) is a drug used to treat patients with AIDS. AZT works by blocking the reverse-transcriptase enzyme used by the human immunodeficiency virus (HIV), the causative agent of AIDS. Do you expect that AZT would have any effect on transposable elements? If so, what type of transposable elements would be affected, and what would be the most likely effect?arrow_forward
