Use a textbook to research: What 3 parts make up a DNA nucleotide?

For the following questions, go to http://nobelprize.org/educational_games/medicine/dna_double_helix/index.html

2. Explain what double helix refers to (be specific in where the molecules are placed and what the helix looks like):

3. What are the rungs of the ladder made of?

4. Which bases are able to connect together to make the rungs?

5. In the game, what happened that created a mutation (what would be the definition of a mutation in terms of DNA)?

6. In your own words, describe how DNA replication occurred during the game. Discuss all the steps in order and in detail beginning with the first double helix.

7. Search the web to find the role of the following enzymes in DNA replication. Be sure to specifically state what they do in a way that you understand. DNA helicase: DNA polymerase:
