Homoplasmic mutations

Webisolation of cybrid clones containing either homoplasmic mutant or homoplasmic wild-type mtDNA against a common nuclear background (18, 19). Second, we transfected a nuclear version of MTATP6, whose codons were converted to the universal genetic codes containing a mitochondrial localization presequence, into the nucleus of mutant cybrids to ... WebEach human cell contains thousands of copies of mtDNA that are usually identical (homoplasmy). However, patients with mitochondrial diseases caused by mutations of mtDNA frequently present a mixture of mutant and wild-type mtDNA within each cell.
