comparative biochemistry

Question 1

describe how comparative DNA analysis can be used to determine the relatedness of two species

Answer 1

By carefully comparing characteristics that define various organisms, researchers can pinpoint regions of similarity and difference

Question 2

how phylogenetic trees are constructed and what information they provide about the evolutionary relationships between species

Answer 2

Relationships between entities are captured by the topology (branching order) and amount of evolutionary change (branch lengths) between nodes.
