   Where does mitochondrial DNA come from?

   • The exclusive maternal inheritance of mitochondrial DNA (mtDNA) is rooted in the unique biology of egg and sperm cells, as well as the cellular machinery involved in fertilization. During sexual reproduction, both egg cells (ova) and sperm cells contribute genetic material to the resulting offspring.

   What is the role of mitochondria in a cell?

   • Nature Cell Biology 26 , 674–686 ( 2024) Cite this article Although it is well described that mitochondria are at the epicentre of the energy demands of a cell, it is becoming important to consider how each cell tailors its mitochondrial composition and functions to suit its particular needs beyond ATP production.

   Where are the mitochondria found?

   • mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP).

   What are the two main parts of mitochondrial DNA?

   • Mitochondrial DNA is made of two major parts: the control region and the coding region. The control region, often called the hypervariable region (HVR), is made of three human hypervariable regions: HVR1, HVR2 and HVR3. The coding region includes genes that encode proteins essential for various mitochondrial functions.

   5 days ago · 1. The vast majority (99%) of the mitochondrial proteome in humans—over 1,100 proteins—is encoded by the nuclear genome. The small 16.6-kb plasmid-like mitochondrial genome (mtDNA) encodes only 13 proteins devoted to producing the chemical energy molecule ATP via oxidative phosphorylation.
