Given That Cells Possess Genes from a Variety of Different

Multiple Choice

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
