Name four facts that serve as evidence for endosymbiosis:
- they have their own DNA, similar to bacterial DNA (i.e. occurs as small loops; DNA not   complexed with histone) - they divide independently of host cell, under their own genetic control (similar to binary   fission) - have small, unique ribosomes similar to bacteria - protein synthesis is inhibited by antibiotics specific for bacteria


     Redundancy vs. No Ambiguity


                                               i.     Redundancy-Multiple codons for same Amino Acid
