- Use the following information to answer the next question. Human genes were integrated into the chromosomes of pig sperm using the procedure of sperm-mediated gene transfer (SMGT). In the first successful SMGT procedure, scientists used an enzyme to integrate three human genes into the chromosomes of pig sperm. Approximately 90% of the resulting pig embryos carried all three human genes in very cell. The presence of the human genes in every cell of a pig embryo is evidence that the genes went through Select one: a. mRNA transcription b. DNA replication c. mRNA translation d. DNA transcription1.
