Explain the term "molecular clock" and describe the types of measurements and comparisons that can be made with this type of clock.

Be sure to answer this question in paragraph form using complete sentences.

In biology, a molecular clock can be described as a method to determine the time for the divergence of species which occurred by the process of evolution. The mutation rates of different molecules are used in this method. The mutation rates for DNA sequences and amino acid sequences are usually considered. The molecular clock can be used to compare and estimate the splitting of a lineage. For example, by this method, one can interpret when the chimpanzees and humans diverged from each other.
