How Mitochondria Protect Themselves from Mutations

  by Ross Anderson, PhD Mitochondria are very interesting and unique organelles. All eukaryotic cells possess them. They are indispensable in a number of cell activities beyond their well-known role of synthesizing the bulk of ATP used to power cells. Mitochondria reproduce at rates that are, for the most part, independent of the cell division […]

Automatic Emergency Brake Found on Molecular Motor

In this article, guest writer Ross Anderson (PhD, biochemistry professor) discusses a new finding about how an ’emergency brake’ works in one of the most vital of all molecular machines, ATP synthase. First, he explains the molecular rotary motor and what it does. Review of “Extrinsic conditions influence the self-association and structure of IF1, the […]
