Both use RNA and DNA are the genetic material 2. Both use the same 20 amino acids 3. Both have ribosomes and DNA and RNA 4. Both have a lipid bilayer cell membrane. 5. Both use L amino acids and D sugars Biologists are also almost certain that eukaryotes evolved only once (i.e., are monophyletic- descendants of a single common ancestor) because they all share: 1. microtubules (composed of the protein tubulin) and actin molecules- cytoskeleton for support or intracellular transport. flagella (or cilia) 2. DNA in chromosomes (intertwined with histone protein) 3. membrane-bound organelles.
