ZeroZero Posted January 27, 2015 Share Posted January 27, 2015 Can anyone tell me how mitochondria are reproduced and how they engage in cell production? I think I understand that mitochondria have their own SDNA/RNA, how then do they get transferred in sexual and conventional cell reproduction - mitosis and myosis? Do they reproduce in a 'convential' way by compying and replicating RNA? I probably have this all wrong ! thank you Z Link to comment Share on other sites More sharing options...
CharonY Posted January 28, 2015 Share Posted January 28, 2015 Meiosis does not apply to mitochondria, they reproduce like bacteria (part of the evidence linking mitochondria to bacterial precursors). Link to comment Share on other sites More sharing options...
ZeroZero Posted January 29, 2015 Author Share Posted January 29, 2015 This is my point. If the mitochondria is excluded from the copying mechanism, how is it passed on from parent(s) to child? How does it copy itself 'at the same time as mitosis occurs? Do simply get 'infected' like catching a bug? Z Link to comment Share on other sites More sharing options...
Endy0816 Posted January 29, 2015 Share Posted January 29, 2015 (edited) During mitosis the individual mitochondria end up roughly distributed between the two cells. They largely replicate at a rate independent of that of the cell they are in. They utilize mtDNA also known as mDNA or simply Mitochondrial DNA. For humans during sexual reproduction, the offspring most typically only inherits the mother's mitochondria.
