What is the primary purpose of genetic screens in cell biology?

What is a major limitation of genetic screens, and how can conditional mutants help overcome this limitation?

Why is it important to combine genetic screens with complementation and epistasis analysis?

You have identified a mutant phenotype affecting cell growth. Which combination of tests would best help you identify the gene responsible and its function?

After inducing mutations in a population of organisms, how would you select for those with defects in cell growth?

How does epistasis analysis help determine the order of proteins in a signaling pathway?

What strategy is used to study lethal mutations in genetic screens?
