Final answer:
The characteristic that is not one of the properties of yeast cells that have made them useful eukaryotic hosts for recombinant DNA studies is their ability to undergo meiosis.
Step-by-step explanation:
The characteristic that is not one of the properties of yeast cells that have made them useful eukaryotic hosts for recombinant DNA studies is their ability to undergo meiosis. Yeasts are eukaryotes and share similarities with human cells, such as their ability to grow in a wide range of conditions and have a high protein production capacity. Additionally, yeasts possess a cell wall, which is a beneficial feature for genetic manipulation. However, unlike some other eukaryotic cells, yeasts do not undergo meiosis.
