Where do mitochondria get their ribosomes?

The mt ribosomal RNAs are encoded in the mitochondrial genome but the genes for mitochondrial proteins are nuclear and the proteins are imported into the mitochondria for ribosome assembly. read more

Mitochondria and chloroplast beloved to be from prokaryotic origin hence seen as bacteria. They were engulfed by eukaryotic cells and have an endosymbiotic relationship. Bacteria have their own DNA which codes for a few proteins in their membranes and ribosomes among other things. read more

The mitochondria has 70S ribosomes which are seen in prokaryotes whereas eukaryotes have 80S ribosomes. In mitochondria the genetic material is present in the form of circular ring which is also seen in case of prokaryotes. Mitochondria have their own genetic material, and the machinery to manufacture their own RNAs and proteins. read more

Best Answer: Mitochondria and chloroplast are supposed to have prokaryotic origin.You can think of them as endosymbiotic bacteria which became cell organelles during evolution. The endosymbiotic relationship of mitochondria with their host cells was popularized by Lynn Margulis. read more
