We previously thought mitochondrial DNA could only be passed on by mothers.
Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.
The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
Star Wars: The Last Jedi leaves many questions about the saga in a galaxy far, far away unanswered. Fortunately, biology may offer a insights on the Force, midi-chlorians, clones, and Rey's lineage.
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
To explain why we have a mitochondria, we have to go back about two billion years to a time when none of the complexity of life as we see it today existed.
If you're planning to become a parent, better lifestyle habits can reduce the risk of obesity in your children.
It's a landmark case but there are many unknowns.
Scientists thought they were closing in on one great new treatment but may have found another instead.
Human population groups worldwide are highly homogeneous genetically. They are in fact 99.5% similar and their anatomical features vary in an uncorrelated fashion over the landscape.
