As a first step toward evaluating "mitochondrial heteroplasmy" in a single
mitochondrion, Pham et al.

This was accomplished by engineering an export sequence to direct the RNA to the
mitochondrion. Once the RNA was in the vicinity of the transport machinery on the mitochondrial surface, then a second transport sequence was required to direct the RNA into the targeted organelle.

While scientists have theorized for at least three decades that mitochondria might be the basis for aging, renewed interest has come from the growing realization that a
mitochondrion is more than just a cellular furnace.
Miao et al (14) found that the
mitochondrion was first shrunk and then swollen during the early and late phases of liver regeneration, which suggested that the permeability of mitochondria first decreased and then increased.
Genetic marking of an individual anterograde or retrograde
mitochondrion will provide further insight into the destination of these mitochondria and their active roles in shaping the function of their host neuron.
It's a ring-shaped structure found inside a cell part called the
mitochondrion. Analyses showed that the modern Asian elephant shares 95.8 percent of its mitochondrial DNA with the woolly mammoth.
If a
mitochondrion were to fail to perform its task of producing ATP, serious illness and other abnormalities would occur.
The tiny
mitochondrion is the focus of intense medical and scientific research in fields ranging from embryology to infectious disease.
In this century, biologists' perspectives on the endosymbiont theory of the origin of the
mitochondrion have changed dramatically.
Once the
mitochondrion is damaged, the cell reverts to fermentation to obtain energy, we can state that the cancer has begun.
