the mitochondria
Explanation:
endosymbiotic theory is prevalent here.
DNA, RNA, and Ribosomes are also all present in all life.

RNA- a single strand of genetic information to go into the ribosome to make proteins
ribosome; the thing that makes proteins!
The mitochondria is an organized organelle, unlike everything else on this list, which is not present in prokaryotes but eukaryotes.
