Purple dye would be a safer choice for food products than the mutagenic blue dye in this example. Explain why the turning on of DNA repair genes might indicate the presence of a carcinogenic pollutant. Sorry Newpaper item is not available. See library reserve copy. The jellyfish is not a chimera, the yeast cell is the transgenic cell because the yeast has genes from 2 different species.
Transformation is the nonspecific uptake of free soluble DNA by a nonrelated cell.
The scientists could also have use transduction to insert the new gene into the yeast. Transduction would require using a viral vector to carry the new gene into the yeast when the virus infects the yeast cell. Conjugation would not be used in this this gene mixing situation. Animal cells and yeast are both eucaryotic. Fidelity is important in DNA because most mutations or mistakes made in replicating DNA are lethal or harmful to the cell.
