Webgene, unit of hereditary information that occupies a fixed position (locus) on a chromosome. Genes achieve their effects by directing the synthesis of proteins. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus. The mitochondria (in animals) and the chloroplasts (in plants) also contain small subsets … WebStudies involving large cohorts of LCLs and controls have investigated mutations in mitochondrial DNA (mtDNA) through the analysis of whole-exome data 6 and gene expression analysis, 7 as well as variation in genotype and copy number variations (CNVs) throughout the genome. 8 Studies performed on single pairs or small groups (n≤20) of …
