2. 51 DNA REPLICATION

3. Question: The arrow indicates… a.The bond between adjacent phosphate and deoxyribose molecules b.The hydrogen bond between complementary nucleotides

4. Hydrogen Bonds Base Pair Nucleotide Phosphate Sugar “Deoxyribose” Shape of DNA “Double Helix”

6. 1.What is the sugar called that DNA is made of? Deoxyribose 2.What are the three components of a Nucleotide? Phosphate, Nitrogen Base, and Sugar 3.What holds together the nitrogen bases in DNA? Hydrogen Bonds

7. 4. If a strand of DNA has the following bases: A T T G C T A T C C G G What would the ‘complimentary’ strand of DNA contain?

10. DNA Replication Exploration Groups of 2-3 Each group needs 4 colors of paper clip – 14 – 9 Using paper clips, we will explore the concept of DNA replication and DNA structure

11. The enzyme “DNA helicase” separating each strand of DNA. 54 How is DNA Copied?

12. 54 How is DNA Copied? A. The enzyme “DNA polymerase” adding nucleotides to each strand of DNA.

14. Your DNA Create the complementary DNA strand DNA: A T G C T T A G C T G DNA:

15. 2 Step Process 1.Helicase breaks H-bonds & untwists the Double Helix 2.DNA Polymerase pairs free nucleotides to open bases. 2 Step Process 1.Helicase breaks H-bonds & untwists the Double Helix 2.DNA Polymerase pairs free nucleotides to open bases. 54 How is DNA Copied? Summary: In order for DNA to replicate….
