In most eukaryotes, the inheritance of mitochondrion and its DNA (mtDNA) is strictly maternal, despite the fact that a spermatozoon can inject up to 100 functional mitochondria into the oocyte during ...
An evolutionary trait of humans and most animals is that they inherit mitochondrial DNA exclusively from the mother, even though the father's spermatozoa have mitochondria. If spermatozoa have ...
Recent research has shed light on the complex processes that cells use to maintain the quality of mitochondrial DNA (mtDNA) for inheritance across generations. These processes are particularly ...
Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...
In September 6 Nature, Sofia Berlin and Hans Ellegren from Uppsala University, Sweden, examine the controversial clonal inheritance theory for vertebrate mitochondrial DNA (mtDNA) by following ...
