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 ...
New research provides insight about the bedrock scientific principle that mitochondrial DNA - the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the ...
The 100 or so organelles in sperm are swamped by hundreds of thousands of mitochondria embedded in each egg cell -- each carrying the 37 genes in mitochondrial DNA. The contribution of only maternal ...
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 ...
Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...
A study published in the latest issue of Science reveals a cellular mechanism involved in the inheritance of genetic mutations. The study also points to a potential treatment that could reduce the ...
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 ...
