Over recent years, the genome-wide CRISPR screen has emerged as a powerful tool for studying the intricate networks of cellular signaling. [52] Cellular signaling is essential for a number of fundamental biological processes, including cell growth, proliferation, differentiation, and apoptosis.
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).

Multiple Annealing and Looping Based Amplification Cycles (MALBAC) is a quasilinear whole genome amplification method. Unlike conventional DNA amplification methods that are non-linear or exponential (in each cycle, DNA copied can serve as template for subsequent cycles), MALBAC utilizes special primers that allow amplicons to have complementary ends and therefore to loop, preventing DNA from ...
Knock-outs have been produced for whole genomes, i.e. by deleting all genes in a genome. For essential genes , this is not possible, so other techniques are used, e.g. deleting a gene while expressing the gene from a plasmid , using an inducible promoter, so that the level of gene product can be changed at will (and thus a "functional" deletion ...
CRISPR-Cas9 genome editing techniques have many potential applications. The use of the CRISPR-Cas9-gRNA complex for genome editing [10] was the AAAS's choice for Breakthrough of the Year in 2015. [11] Many bioethical concerns have been raised about the prospect of using CRISPR for germline editing, especially in human embryos. [12]
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 ...
The yeast genome is highly accessible to manipulation, hence it is an excellent model for genome engineering. The international Synthetic Yeast Genome Project (Sc2.0 or Saccharomyces cerevisiae version 2.0 ) aims to build an entirely designer, customizable, synthetic S. cerevisiae genome from scratch that is more stable than the wild type.
Whole genome sequencing (WGS) is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. [2] This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast .
