Extrachromosomal DNA (ecDNA) in cancer pathogenesis
Inheritance of extrachromosomal DNA differs from the inheritance of nuclear DNA found in chromosomes. Unlike chromosomes, ecDNA does not contain centromeres and therefore exhibits a non-Mendelian inheritance pattern that gives rise to heterogeneous cell populations. In humans, virtually all of the … Visa mer Extrachromosomal DNA (abbreviated ecDNA) is any DNA that is found off the chromosomes, either inside or outside the nucleus of a cell. Most DNA in an individual genome is found in chromosomes contained in the nucleus. … Visa mer Mitochondrial Mitochondria present in eukaryotic cells contain multiple copies of mitochondrial DNA (mtDNA) in the Visa mer Sometimes called EEs, extrachromosomal elements, have been associated with genomic instability in eukaryotes.
