  2. Genome-wide CRISPR-Cas9 knockout screens - Wikipedia

    en.wikipedia.org/wiki/Genome-wide_CRISPR-Cas9...

    Targeted gene knockout using CRISPR/Cas9 requires the use of a delivery system to introduce the sgRNA and Cas9 into the cell. Although a number of different delivery systems are potentially available for CRISPR, [37] [38] genome-wide loss-of-function screens are predominantly carried out using third generation lentiviral vectors.

  3. Synthetic genetic array - Wikipedia

    en.wikipedia.org/wiki/Synthetic_genetic_array

    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). [9]

  4. Yeast deletion project - Wikipedia

    en.wikipedia.org/wiki/Yeast_deletion_project

    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 ...

  5. Functional genomics - Wikipedia

    en.wikipedia.org/wiki/Functional_genomics

    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 ...

  6. Gene targeting - Wikipedia

    en.wikipedia.org/wiki/Gene_targeting

    [13] [14] Gene-targeting is a specific biotechnological tool that can lead to small changes to the genome at a specific site [2] - in which case the edits caused by gene-targeting would count as genome editing. However gene targeting is also capable of inserting entire genes (such as transgenes) at the target site if the transgene is ...

  7. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    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]

  8. Zygosaccharomyces bailii - Wikipedia

    en.wikipedia.org/wiki/Zygosaccharomyces_bailii

    For example, by utilizing acetic acid, the yeast can raise the pH of pickles sufficiently to allow the growth of less acid-tolerant bacteria. [5] Besides, as with other yeasts, the concentration of fermentable sugar in a product affects the rate of spoilage by Z. bailii , e.g. the yeast grows faster in the presence of 10% (w/w) than 1% (w/w ...

  9. Gene redundancy - Wikipedia

    en.wikipedia.org/wiki/Gene_redundancy

    Redundant genes are more likely to survive when they are involved in complex pathways and are the product of whole genome duplication or multifamily duplication. [13] The currently accepted outcomes for single gene duplicates include: gene loss (non-functionalization), functional divergence, and conservation for increased genetic robustness. [11]
