Typically, humans inherit mitochondria and mitochondrial DNA from their mothers only. But using sequencing data from the mitochondrial genomes of members from three unrelated families, researchers ...

Normal metabolic activity produces reactive oxygen species (ROS) that, if not eliminated, can damage cellular components. As a result, ROS from overactive mitochondria are frequently cited as a source ...

Mitochondria are surrounded by two or more membranes, and the innermost of these membranes is very similar in composition to bacteria. Both mitochondria and chloroplast have their own DNA ...

This structure is so important because it is the site at which the cell's DNA is housed and the ... evolving into present-day mitochondria and chloroplasts. This proposed origin of mitochondria ...
