From Microbial Beginnings to the Ageing Clock
In every cell of our body, a quiet evolutionary miracle continues to unravel. Deep within us, specific old microbial kinds really did not just vanish gradually– they integrated into our biology, coming to be the energy engines that sustain life as we understand it. Mitochondria, once free-living bacteria, still lug their own DNA and now operate as the central power carriers within human cells, creating ATP– the fuel of life. This bacterial DNA continues independently from our nuclear genome, making mitochondria not just remarkable biologically, however functionally sovereign parts of our being.
The Mitochondrial Heritage:
Mitochondria are distinct: they duplicate independently, lug their very own 37 -genetics round genome, and are inherited solely from the mother. Their ancient symbiosis with early eukaryotic cells was a defining moment in evolution, not simply survival, yet a collaboration that allowed multicellular life to flourish. These ancient bacterial residues became the energised heart beat of intricate microorganisms, and they stay vital. Nothing else in our biology operates with this degree of genomic freedom inside the cell. There is nothing else organelle with its own stable, acquired DNA aside from the center and mitochondria.
