Given that cells possess genes from a variety of different ancestral sources, deciding which to use for evolutionary relatedness comparisons can be complicated. The best candidates for determining phylogenetic relationships tend to be ________________.
A)informational genes because they operate singly and uniquely
B)metabolic activity-related genes because they operate singly and uniquely
C)informational genes because they encode components which are parts of large complexes and conservation of structure is required
D)metabolic activity-related genes because they encode enzymes which are parts of large complexes and conservation of structure is required
E)all gene types provide the same phylogenetic accuracy

Informational genes are the best candidates for determining phylogenetic relationships because they encode components which are parts of large complexes and conservation of structure is required. This allows for reliable comparisons of homologous sequences across different taxa.
