URA3 is often used in yeast research as a "marker gene", that is, a gene to label chromosomes or plasmids. URA3 encodes Orotidine 5'-phosphate decarboxylase (ODCase) , which is an enzyme that catalyzes one reaction in the synthesis of pyrimidine ribonucleotides (a component of RNA ).
In yeast and bacteria, OMP decarboxylase is a single-function enzyme.However, in mammals, OMP decarboxylase is part of a single protein with two catalytic activities.This bifunctional enzyme is named UMP synthase and it also catalyzes the preceding reaction in pyrimidine nucleotide biosynthesis, the transfer of ribose 5-phosphate from 5-phosphoribosyl-1-pyrophosphate to orotate to form OMP.
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 ...
Gene knockdown is an experimental technique by which the expression of one or more of an organism's genes is reduced. The reduction can occur either through genetic modification or by treatment with a reagent such as a short DNA or RNA oligonucleotide that has a sequence complementary to either gene or an mRNA transcript.
Florida's attorney general said on Thursday she filed a lawsuit against the U.S. Federal Emergency Management Agency for allegedly discriminating against hurricane victims who supported President ...
Two people have been arrested and are facing charges of felony child abuse after a one-month-old baby was discovered in the median of a road Christmas morning.
