A gel electrophoresis migration pattern displaying polymerase chain reaction (PCR) products shows four strong bands. The lengths of the four pieces of DNA are approximately in the ratio of 1:2:3:4. The longest band is cut out of the gel, and PCR is repeated with the same primers. Again, a ladder of the same four bands appears in the gel. What does this result reveal about the structure of the encoded protein?A) The protein is a tetramer of a single peptide. B) Up to four copies of the DNA ligate to form circular DNA molecules. C) Four copies of the protein‑coding gene occur in the genome. D) The encoded protein contains four repeats of a specific sequence. E) Portions of the protein are encoded by four different genes.
