Disruption of “All” Yeast Genes
• Approx 6000 genes
• Make 6000 sets of disruption primers
• Disrupt each gene in a diploid
• Dissect all 6000 diploids
– Identify set of essential genes
– Identify set of non-essential genes
Yeast “Knockout” Library
• Delete one copy of each gene in diploid
– 5,916 “genes” deleted
– 5,916 diploid strains constructed
• Dissect to determine if gene is essential
– 1,105 genes = essential
– 18.7% of genes = essential
• Construct an ordered library of haploids for non-
essential genes
– 4,811 mutant strains in library
