Challenge Problems
Push your limits with advanced challenges
Given a scenario where DNA replication is disrupted and polymerase adds incorrect bases during replication, describe how this could affect genetic information and evolution.
💡 Hint: Consider the role of mutations in populations and natural selection.
Design an experiment to test if a new enzyme discovered in E. coli can also serve as a DNA polymerase and compare it to the existing enzyme.
💡 Hint: Think about how to set up controls for comparison.
