General Biology Sharp Name: Block: Date: DNA Replication Worksheet 1. Draw a nucleotide, labeling each of the three important parts. 2. Identify the four bases found in DNA. 3. Show which bases bond together in DNA. 4. Make a drawing that clearly shows how nucleotides come together to make DNA. (Include at least four pairs of bases here.) 5. Describe what is meant by “double helix”. 1 of 2 General Biology Sharp 6. In both mitosis and meiosis, DNA is copied (replicated) before either process can happen. Use what you have learned about the structure of DNA to propose a mechanism that can turn one DNA strand into two. 7. Research DNA replication, and then compare and contrast your proposed mechanism for DNA replication to that described in the textbook you are using. Your Proposed Mechanism DNA Replication in Textbook 8. Briefly explain why perfection in DNA replication is important. 2 of 2
