Answer:
The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation.
Explanation:
The molecular clock is also known as the “evolutionary clock” or “gene clock”. These was studied by scientists suchs as Darwin, and it made possible for paleontologists to study humanity evolution. <em>Through this idea we talk about the biological concept of heredity: we inherit information in the form of genetic molecules (usually DNA) from the previous generation</em>. This is possible thanks to Mutation. In mutation, DNA and protein sequences evolve DNA and protein sequences evolve over time and among different organism.
