when a pcr amplification was performed on human genomic dna, multiple products of varying sizes were obtained, including one of the expected size. which of the following modifications to the protocol is most likely to eliminate the extra pcr products.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
