RWS-15 Does Mitochondrial DNA have a "hidden purpose" ?
Some parts of this site are currently incomplete & will be updated asap
Other parts will change continually so use “Refresh” in your browser !!
There is extensive use of “Tooltips” text to support learning which do not seem to render on a Smartphone, so this site is best viewed via a computer’s HD monitor
Learning -> Resources Available, All Work is Subject to DHRF's "GD"
“Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus”
“Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins”
“Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from the circular genomes of bacteria engulfed by the early ancestors of today’s eukaryotic cells. This theory is called the endosymbiotic theory. In the cells of extant organisms, the vast majority of the proteins present in the mitochondria (numbering approximately 1500 different types in mammals) are coded for by nuclear DNA, but the genes for some, if not most, of them are thought to have originally been of bacterial origin, having since been transferred to the eukaryotic nucleus during evolution”
Further Content Awaiting Future Release
Sorry ! The reasons for this are due to the constraints we are currently under…
Baseline: rws_15_md_R01;B01
In view of DHRF’s commitment to support learning, there is a much higher “learning content” in the Research Work Streams than would otherwise be the case… Please be aware of that ↩
