This is also a theory that scientists have used to discover how chloroplasts became organelles in plants. You are exactly right in your description of the theory and I agree that mtDNA is incredibly interesting. I can't wait to see where scientists take this research in the future.<br />Posted by Brianna LucianiAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9008122866340502585.post-79912176348550190652019-09-29T17:53:59.790-07:002019-09-29T17:53:59.790-07:00Yes, there have been reported cases of paternal mt...Yes, there have been reported cases of paternal mtDNA found in offspring. Typically, this leads to the offspring not surviving or having diseases related to mtDNA. The article from paragraph two of the post does mention this briefly but, like you, I have also found that it is very rarely occurring.<br />Posted by Brianna LucianiAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9008122866340502585.post-61291137254838535062019-09-27T12:08:59.924-07:002019-09-27T12:08:59.924-07:00Mitochondrial DNA is very interesting and it opens...Mitochondrial DNA is very interesting and it opens many possibilities for developing maternal lineages. This could help evolutionary biologists to study lineages and help to create phylogenies of species. Mitochondrial DNA could also be used to see how related two people are to one another by looking at how much their DNA in the mitochondria has changed. I believe the discovery of mitochondrial DNA led to the Endosymbiotic Theory. This is a theory that explains the origin of eukaryotic life. The theory suggests that a cell engulfed a prokaryotic cell and contained it but did not destroy the cell. This cell, now inside the parent cell was what became the mitochondria. The evidence lies in that the DNA of mitochondria lies within the mitochondria the way DNA lies in many prokaryotic cells. Not in the nucleus that is.<br /><br />Posted by John MarianoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9008122866340502585.post-78382654029876744712019-09-27T11:35:58.148-07:002019-09-27T11:35:58.148-07:00In an additional course that I am taking this seme...In an additional course that I am taking this semester, we have been discussing the molecular and evolutionary history of mitochondria. The endosymbiotic theory states that the evolution of eukaryotic cells originates from prokaryotic organisms. This theory also describes how mitochondria and possibly other organelles (plastids, chloroplasts) represent a formerly free-living prokaryote that was ingested by another. It would be interesting to find some more background information on to how the the mitochondria became maternally inherited. <br />-Elise BabulaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9008122866340502585.post-47857923645613778622019-09-26T18:53:25.333-07:002019-09-26T18:53:25.333-07:00I find it very fascinating that companies such as ...I find it very fascinating that companies such as 23andme possibly find even better readings for maternal mitochondrial DNA. It makes me wonder about the mitochondrial cell cycle that we do not learn about in depth. I also wonder how or if mitochondrial DNA differs in humans. Mitochondria themselves are likely more similar to prokaryotic cells due to their lack of a nuclear membrane. Therefore I do not understand how there is any significant difference between maternal and paternal mitochondrial DNA for this reason.<br /><br />Posted by Isaac CollibeeAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9008122866340502585.post-10073613902375512019-09-26T15:17:59.221-07:002019-09-26T15:17:59.221-07:00I agree, I think mitochondrial DNA can be key to s...I agree, I think mitochondrial DNA can be key to solving many diseases, I do hope this researched is pursued.

However, has there ever been cases in which a portion of the father's mitochondrial DNA has appeared inside human cells? From what I could find on the internet, it is very rare for this phenomenon to occur, but it could happen. <br />Posted by Lauren ShoneAnonymousnoreply@blogger.com
