Summary:
Scientists have found a clue to why one type of DNA is passed down to children by their mothers - but not their fathers. DNA inside energy-producing organelles called mitochondria is destroyed in a worm dads sperm shortly after it fertilizes an egg, researchers report online. A protein called CPS-6 cuts apart the mitochondrial DNA in the male sperm, blocking production of the proteins that the mitochondria need to power the cell. Lingering paternal mitochondrial DNA might hurt developing embryos, the researchers say.
"Protein Ruins Dad's Mitochondria" is from the July 23, 2016 issue of Science News.
