About This Quiz & Worksheet

How does DNA replication take place, and how did the scientific community make this great discovery? These are the main questions you'll be asked in this quiz and worksheet combo. In addition to the details of the crucial DNA replication experiment, you'll need to know about the three proposed models of DNA replication and how two of them were disproved.

Quiz & Worksheet Goals

Use these assessment tools to test your knowledge of the following:

  • The cellular process of copying DNA
  • Three proposed models of DNA replication
  • The experiment that uncovered the now-accepted model of DNA replication
  • The N-15 isotope and N-14 atom used in the DNA replication experiment

Skills Practiced
