我觉得，楼主定位还准确。只不过要把意思搞清楚。C选项：True bacteria and eukaryotes employ similar types of genetic coding. 由文中：For instance, they translate genetic information into proteins according to the same type of genetic coding.所支持。所以不选。E选项Amino acid sequences of enzymes are uniform for eukaryotic and prokaryotic organisms.恰恰与文中the details in the two forms are different and characteristic of the respective forms. For example, the amino acid sequences of various enzymes tend to be typically prokaryotic or eukaryotic.相反，所以为答案。
