1. Give at least two differences between prokaryotic and eukaryotic DNAs
8. Using recombinant DNA techniques (which willbe described in Chapter 9), it is possible to take theDNA of a gene from any source and place it on achromosome in the nucleus of a yeast cell. Whenyou take the DNA for a human gene and put it into ayeast cell chromosome, the altered yeast cell canmake the human protein. But when you remove theDNA for a gene normally present on yeast mitochondrial chromosomes and put it on a yeast chromosome inthe nucleus, the yeast cell cannot synthesize the correctprotein, even though the gene comes from the sameorganism. Explain. What would you need to do to ensurethat such a yeast cell could make the correct protein?
