The psychic is, quite literally, the new kid on the block as far a psychics go; his name is Tyler Henry, and apparently the basic cable channel E! is really pushing a TV series featuring him, Hollywood Medium With Tyler Henry. His website describes him thusly:
Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast. In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.
The mitochondrial genome encompasses between one and two thousand nuclear-DNA-encoded mitochondrial genes and thousands of copies of the mitochondrial DNA (mtDNA). mtDNA has a high mutation rate, and de novo mtDNA mutations create a mixture of mutant and normal mtDNAs in cells, a state known as heteroplasmy. Cell body-This main part has all of the necessary components of the cell, such as the nucleus (contains DNA), endoplasmic reticulum and ribosomes (for building proteins) and mitochondria (for making energy).
