- Both mitochondria and plastids are believed to have originated through endosymbiosis, a process where prokaryotic cells were engulfed by early eukaryotic cells. - This evolutionary history explains why they retain their own DNA (circular, similar to bacterial DNA) and ribosomes (70S type, similar to bacterial ribosomes), separate from the nuclear DNA and cytoplasmic ribosomes (80S type) of the host cell.
Which cell organelles have their own DNA and Ribosomes ?
