Summary Introduction
Introduction:
Three domains includes Archaebacteria, prokaryotes and eukaryotes. Archaebacteria has the 70S ribosome and plasma membrane. Prokaryotes also has both 70S and plasma membrane. Eukaryotes also 70S and plasma membrane. These are the two unique characteristics found in all three domains.
