Mitochondria are able to replicate by themselves. When mitochondria replicate, a copy of the mitochondrial DNA is present in the daughter mitochondria as well. This is how they are passed on. Edit: Mitochondrial DNA is passed on maternally (ie the mito. that replicate in a new organism are derived from the mother/egg).

mitochondrial dna is not changed when passed to offspring. dna in the nucleus can be changed due to dominant and recessive traits.


No. Mitochondrial diseases are passed on only by mothers. So, she will pass it to her son. But her son will not be able to pass it to his children, since mitochondrial diseases are passed solely by women. Most (if not all) mitochondrial DNA are of maternal origin.


Mitochondrial DNA is localized in the matrix of the mitochondria.


Mitochondrial DNA comes from the mother, so the mother's maternal line and all her children share the same mitochondrial DNA.


Mitochondrial DNA codes for 13 mitochondrial proteins, 16S and 12S rRNA and 22 tRNAs


In most organisms, including humans, the mitochondrial DNA is inherited from the mother.


An Individual inherits their mitochondrial DNA from the mother. Mitochondrial DNA is the smallest chromosome and was the first part of the human genome to be sequenced.


None, mitochondrial DNA is inherited from the mother.


Mitochondrial DNA - journal - was created in 1980.



mtDNA is mitochondrial DNA.


Yeast's is (~78kb), while human's is about 17kb


It resembles mitochondrial DNA


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.



Mitochondrial DNA is almost universally inherited from one's mother. I heard of a case of a man in Italy inheriting his mitochondrial DNA from his father, but I consider it likely he was also sterile--if indeed that did occur.


No, mitocondrial DNA is for the cell and Nulear DNA is for your body.


Mitochondrial DNA is passed on solely from mother to child. The is usually the case with most species, including humans.


It is DNA that is found in the mitochondria of a cell. By:justin


You inherit your Mitochondrial DNA from your mother. However, you inherit your DNA from both parents. Although you could have a larger percentage from one parent than the other.


as big as it wants to be


Damage in mitochondrial DNA will have the most effect on cellular respiration. This is due to the fact that the surface area will be damaged.


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.


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


Apart from the nucleus, cell organelles like chloroplasts and mitochondria also contain DNA which encode enzymes necessary for their functions. Did you also know that your mitochondrial DNA has solely come from your mom's mitochondrial DNA? That's because mitochondrial DNA is maternally inherited just as the Y-chromosome is paternally inherited.
