aNearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitohondrial DNA or mtDNA). 几乎每个细胞在人的身体有同样脱氧核糖...

Many viruses can insert their genes into the DNA of their hosts. Ordinarily, that is a bad thing, because cells sosubvertedchurn outmore copies of the virus. In this case, the hope was that infection would be a good thing. Thedefanged viruscould not reproduce. But it was capable of repl...
Mitochondria contain their own genome, known as mitochondrial DNA (mtDNA), which is circular, intron-free, double-stranded, haploid, and approximately 16.6 kb8. The mitochondrial DNA copy number (mtDNA-CN) refers to the number of mtDNA copies per cell and it can be conveniently determined from...
One is caused byfaulty genesin the nuclear DNA, the DNA we inherit from both our parents and which makes us who we are. The other is caused by faulty genes in the mitochondria's own DNA. Mito caused by faulty mitochondrial DNA is passed down through the mother. But the risk of disease...
The disease in question is Leber hereditary optic neuropathy (LHON). A defective gene in a patient’s mitochondria — the tiny structures that provide a cell’s energy — causes retinal cells to die. That leads to sudden and rapid loss of sight, with many1becoming legally blind within a ye...
