A geneticist modifies a strain of yeast to express a drought-resistant protein. Out of 200 cells, 45% show expression early, 30% show delayed expression, and the rest fail. Among those that fail, 1/4 are selected for backup cultures and fully express when rebooted. How many successfully express the protein after reboot?

Geneticist Modifies Yeast to Express Drought-Resistant Protein: Breakthrough in Drought Resistance via Yeast Strain Optimization In a landmark study led by a team of geneticists, researchers have successfully engineered a strain of yeast to express a drought-resistant protein, opening new pathways for biotechnological applications in agriculture and industrial fermentation. By leveraging precise genetic modifications, the team aimed to enhance the yeast’s cellular resilience under water-deficit conditions—critical for developing robust, stress-tolerant microbial systems. ### Yeast Expression Outcomes Reveal Key Performance Patterns Of the initial 200 yeast cells modified in the experiment, the expression of the drought-resistant protein showed significant variability:
