Yes,mitochondria have their own DNA.So they replicate themselves.
Mitochondrion
Both contain DNA
Yes, mitochondria have dissimilar DNA to nuclear DNA. That is because mitochondria arose endosymbiotically as an invasion of an early eukaryotic (nucleated) cell by a purple bacterium in a relationship which was subsequently symbiotic. Many mitochondrial substances are encoded for by the mitochondrial DNA. Some others important to mitochondrial function are also encoded by nuclear DNA. But yes, the mitochondrion would have to carry out its own transciption to make the products it itself coded for. As the mitochondrion was once an autonomous bacterium (way back in Cambrian or Precambrian times), its genome would be different to the actual genome of the organism's cell (in the nucleus) in which it resides. And thus for the large part it would function utterly independently. But there may be inteferences that evolved over the billions of years since the system's origin. As I said the nucleus itself encodes for at least some products essential to mitochondrial function.
Mitochondrion is singular, mitochondria is the plural form. So the question should be written "What does a mitochondrion do" or "What do mitochondria do". The primary function of mitochondria is the production of ATP via the Krebs Cycle; basically, the mitochondria are where we turn sugar into energy. They have several other functions as well.
The mitochondrion functions similarly for both plant cells and animal cells, producing the ATP used for energy. It can be considered the cell's power plant.
Mitochondrion
If you are refering to the mitochondria/mitochondrion then no because the mitochondria is used in our cells while nuclear DNA are used for things like making bombs i would assume.
Nucleus, DNA, mitochondrion, and more
Mitochondrion
Yes, they do replicate their own mitochondrial DNA or mt DNA
The nucleus More precisely the genes which may be in the nucleus or outside nucleus in the cytoplasmic cell organelles such as the chloroplast and the mitochondrion
Both contain DNA
Chloroplasts; Mitochondrion
