B) Possessing plasmids is a feature that would disfavor bacteria as hosts.
C) Differences between prokaryotes and eukaryotes often tilt the balance toward bacteria as host cells for expressing eukaryotic genes.
D) Bacteria are often favored as hosts because little is known about yeast genetics.
E) Yeasts are often favored as hosts because little is known about bacterial genetics.

Question

Quizplus · Accepted Answer

Bacteria can naturally carry plasmids, small circular DNA molecules that can replicate independently. This makes them a convenient host for recombinant DNA because the plasmid can be engineered to carry the desired gene and then easily replicated within the bacterial cell. Yeasts also have plasmids, but they are less commonly used in genetic engineering because they are more difficult to work with. Therefore, possessing plasmids is a feature that favors bacteria as hosts.
