  2. 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 ...

  3. Deletion (genetics) - Wikipedia

    en.wikipedia.org/wiki/Deletion_(genetics)

    Deletion on a chromosome. In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is left out during DNA replication.

  4. Deletion mapping - Wikipedia

    en.wikipedia.org/wiki/Deletion_mapping

    In genetics and especially genetic engineering, deletion mapping is a technique used to find out the mutation sites within a gene. The principle of deletion mapping involves crossing a strain which has a point mutation in a gene, with multiple strains who each carry a deletion in a different region of the same gene.

  5. 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).

  6. Mutagenesis (molecular biology technique) - Wikipedia

    en.wikipedia.org/wiki/Mutagenesis_(molecular...

    Types of mutations that can be introduced by random, site-directed, combinatorial, or insertional mutagenesis. In molecular biology, mutagenesis is an important laboratory technique whereby DNA mutations are deliberately engineered to produce libraries of mutant genes, proteins, strains of bacteria, or other genetically modified organisms.

  7. Disease gene identification - Wikipedia

    en.wikipedia.org/wiki/Disease_gene_identification

    Disease gene identification is a process by which scientists identify the mutant genotypes responsible for an inherited genetic disorder. Mutations in these genes can include single nucleotide substitutions, single nucleotide additions/deletions, deletion of the entire gene, and other genetic abnormalities.

  8. Chromosomal deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_deletion_syndrome

    The proximal boundary of the WHSCR was defined by a 1.9 megabase terminal deletion of 4p16.3. This allele includes the proposed candidate genes LEMT1 and WHSC1. This was identified by two individuals that exhibited all 4 components of the core WHS phenotype, which allowed scientists to trace the loci of the deleted genes.

  9. Muller's morphs - Wikipedia

    en.wikipedia.org/wiki/Muller's_morphs

    After Muller's classification of gene mutation, an isomorph was described as a silent point mutant with identical gene expression as the original allele. [4] [5] m/Df = m/Dp Therefore, with respect to the relationship between the original and mutated genes, one cannot talk about the effects of dominance and/or recessiveness. [4] [5] [6]
