Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations ...

DNA in mitochondria; has some characteristics in common with eubacterial DNA and typically consists of a circular molecule that lacks histone proteins and encodes some of the rRNAs, tRNAs, and ...

Mitochondria are the small organelles that generate the energy our bodies need to grow, move, and stay healthy. As mitochondria have to constantly adjust their function to meet the cell's energy ...

Did you know that you have a second genome? Small cellular organelles called mitochondria contain their own circular DNA. What happens to your cells when this DNA mutates? Similar to the nuclear ...

An evolutionary "loophole" might explain why males of many species live shorter lives than their female counterparts, a new study finds. The loophole lies in the mitochondria, the energy-generating ...

AUTISM is a puzzling phenomenon. In its pure form it is an inability to understand the emotional responses of others that is seen in people of otherwise normal—sometimes above normal—intelligence.

A genetic mystery in white sharks (formerly great white sharks) has stumped scientists for over 20 years. Between three major populations of the sharks, differences in mitochondrial DNA have raised ...

One in four Gulf War veterans suffers from Gulf War Illness, a condition characterized by unexplainable chronic fatigue, muscle pain and cognitive dysfunction. New research finds for the first time ...
