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 ...
To ensure that protein synthesis is inhibited during the entire chase, cycloheximide is often spiked into the sample every few hours. In yeast, deletion strains are frequently used to assess protein stability over time with cycloheximide chases. For example, yeast strains lacking critical degradation machinery such as chaperones, E3 ligases ...
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).

Delitto perfetto (Italian: [deˈlitto perˈfɛtto]) is a genetic technique for in vivo site-directed mutagenesis in yeast. This name is the Italian term for "perfect murder", and it refers to the ability of the technique to create desired genetic changes without leaving any foreign DNA in the genome.
For example, the ste11 transcript in Schizosaccharomyces pombe has a 2273 nucleotide 5′ UTR [4] while the lac operon in Escherichia coli only has seven nucleotides in its 5′ UTR. [5] The differing sizes are likely due to the complexity of the eukaryotic regulation which the 5′ UTR holds as well as the larger pre-initiation complex that ...
NMD is a cellular mechanism that degrades mRNAs containing premature termination codons (PTCs), which can arise from mutations. Comprehensive analyses large scale genetics and gene expression datasets have enabled the systemic identification of the complex rules governing NMD efficiency, and quantification of their relative importance and effect size.

Structure of a gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell.
This system has allowed researchers to manipulate a variety of genetically modified organisms to control gene expression, delete undesired DNA sequences and modify chromosome architecture. The Cre protein is a site-specific DNA recombinase that can catalyse the recombination of DNA between specific sites in a DNA molecule.
