Using this sample model as a guide, create a molecular clock model. Use the flowchart tools in your word processing program to make your model. Make sure the mutations are clearly visible in the strand. Consider using a different font color for the mutations. Use the Insert Image button to insert a screenshot of your model in the answer space provided. Researchers at the University of California, Berkeley, report that the gene that codes for specific hemoglobin protein experiences mutations in its nitrogen bases. The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split. This model gives an example of how a gene can act like a molecular clock. It shows the lineage of two species that diverged from a common ancestor. As the two species diverged, they experienced different mutations in the DNA sequence, as shown in the image.
