Synthetic genetic array analysis is generally conducted using colony arrays on petriplates at standard densities (96, 384, 768, 1536). To perform a SGA analysis in S.cerevisiae, the query gene deletion is crossed systematically with a deletion mutant array (DMA) containing every viable knockout ORF of the yeast genome (currently 4786 strains).

The yeast deletion project, formally the Saccharomyces Genome Deletion Project, is a project to create data for a near-complete collection of gene-deletion mutants of the yeast Saccharomyces cerevisiae. Each strain carries a precise deletion of one of the genes in the genome. This allows researchers to determine what each gene does by comparing ...
After Benzer demonstrated the power of the T4 rII system for exploring the fine structure of the gene, others adapted the system to explore related problems.For example, Francis Crick and others used one of the peculiar r mutants Benzer had found (a deletion that fused the A and B cistrons of rII) to demonstrate the triplet nature of the genetic code.
Gene knockout by mutation is commonly carried out in bacteria. An early instance of the use of this technique in Escherichia coli was published in 1989 by Hamilton, et al. [2] In this experiment, two sequential recombinations were used to delete the gene. This work established the feasibility of removing or replacing a functional gene in bacteria.
Respiratory illness activity – a measure of how often conditions like the common cold, flu, COVID-19, and respiratory syncytial virus are diagnosed – is currently "high" in the United States ...
Alkylating agents (e.g., N-ethyl-N-nitrosourea (ENU). These agents can mutate both replicating and non-replicating DNA. In contrast, a base analogue can mutate the DNA only when the analogue is incorporated in replicating the DNA. Each of these classes of chemical mutagens has certain effects that then lead to transitions, transversions, or ...

From January 2008 to December 2012, if you bought shares in companies when William C. Ballard, Jr. joined the board, and sold them when he left, you would have a -5.2 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
