Molecular scientists can read the dna code and compare the dna of different organisms. this concept is used in molecular clocks to determine which of the following? . a) morphological relationships . b) molecular phylogenies . c) evolutionary relationships.

 the more closely organisms are related, the more similar the DNA sequences are. It's also used to determine evolutionary (phylogenetic) relationships. For example, DNA analysis showed that hyenas, although they look like dogs, are more closely related to cats. so
