Unlike nuclear DNA, whose genes are rearranged in the process of recombination, there is usually no change in mtDNA from parent to offspring. Because of this, and the fact that the mutation rate of mtDNA is higher than that of nuclear DNA and is easily measured, mtDNA is a powerful tool for tracking matrilineage, and has been used in this role for tracking the ancestry of many species back hundreds of generations. Human mtDNA can also be used to identify individuals. == ==
Mitochondria DNA is from endosymbiotic origins. Basically, this means a long time ago when regular eukaryotic cells engulfed energy producing bacteria, those bacteria had their own DNA that never changed while our own cell nuclear DNA changes every time we have a recombination (reproduction). Also, everyones mitochondria DNA is nearly the exact same, while our nuclear DNA is much more variant.
The basic difference between the nuclear DNA and the mitochondrial DNA is that the nuclear DNA is linear in shape while the circular DNA is present in the mitochondria. Apart from this, the mode of replication also differs in both of them. While the replication in the nuclear DNA is normal the replication in the mitochondria takes by rolling circle model.
Mitochondrial DNA is used only by the mitochondria, which are bacteria-like organelles. Mitochondra contain no DNA for other parts of the human body.
Mitochondrial DNA is inherited only from the mother, where as nuclear DNA is a splicing of both parents' DNA.
Only one copy of nuclear DNA exists in any cell. thousands of copies of mitochondrial DNA exist in every cell.
Nuclear DNA, which is found in the nucleus, is inherited from both parents. On the other hand, mtDNA is found in the mitochondria and, in most multicellular organisms, is inherited from the maternal lineage. Nuclear DNA is arranged in linearly organized chromosomes while mtDNA is organized as a circular chromosome. Unlike nuclear DNA, whose genes are rearranged in the process of recombination, there is usually no change in mtDNA from parent to offspring. Because of this, and the fact that the mutation rate of mtDNA is higher than that of nuclear DNA and is easily measured, mtDNA is a powerful tool for tracking matrilineage, and has been used in this role for tracking the ancestry of many species back hundreds of generations.

Mitochondrial DNA (mtDNA) is much smaller than nuclear DNA (nDNA). Nuclear DNA has approximately 3.9 billion base pairs in its entire sequence; mtDNA has only 16,500 pairs
No, mitocondrial DNA is for the cell and Nulear DNA is for your body.
It is circular.

Nuclear DNA is the information molecule of an organism. It has all the codes for all the proteins our body can make. Mitochondrial DNA however is mainly involved in replication of mitochondria organelle. Main job of mitochondria is the energy production in cell.
Yes
An organisms complete set of nuclear DNA is a genome. Organism's inherit all of their mitochondrial DNA from the female parent.
There are two kinds of DNA in a eukaryotic cell, nuclear and mitochondrial. Nuclear is found in the nucleus and mitochondrial is found in the mitochondria. However, not as many people know about mitochondrial DNA and the only time it is ever refered to is when you are tracking the mother's side of a family with DNA. So for the most part, DNA is found in the nucleus.Eukaryote DNA is located in the nucleus of the cell.

Yes
Environmental DNA (eDNA) is nuclear or mitochondrial DNA that is released from an organism into the environment
Yes
No. Not all cells have a nucleus, which contains nuclear DNA; but all cells have mitochondria, which have their own DNA, called mitochondrial DNA, or mDNA. In humans, the cells that lack a nucleus and therefore nuclear DNA, are mature red blood cells, but they do have mitochondria and mitochondrial DNA.
The nucleus (called nuclear DNA) and Extra nuclear DNA source: 1- chloroplasts (cpDNA) and 2- Mitochondrial (mtDNA).
An organisms complete set of nuclear DNA is a genome. Organism's inherit all of their mitochondrial DNA from the female parent.
It exists because the DNA in mitochondria is duplicated without the checkpoints that nuclear DNA duplication has. Mitochondrial DNA disorders may occur spontaneously and relatively often.

The ribosomes of chloroplasts closely resemble bacterial ribosomes, while mitochondrial ribosomes show both similarities and differences that make their origin more difficult to trace.
Mitochondrial DNA - journal - was created in 1980.
