The tertiary structure of DNA polymerase can be viewed using Chime. The structural similarities between human , hamster , fly , yeast , and mouse were analyzed to determine conservation and homology among various species. Multiple sequence alignment was performed to determine conservation and homology among species. Phylogenetic Tree Figure 7. Phylogenetic tree for the delta catalytic subunit of DNA polymerase for hamster , mouse , human , fly , and yeast .
Percentages represent the degree of homology among amino acid sequences.
