1. What are the three components of a nucleotide? (HINT: What were the three components used in putting the model together? Remember that Adenine, Guanine, Cytosine, and Thymine are all Nitrogen Bases!) Refer to your DNA article if you are still unsure. 2. What is the name of the sugar molecule in the DNA helix? 3. Suppose you know that the sequence of bases on one DNA strand (one side of the DNA ladder) is AGCTCAG. What is the sequence of the bases on the opposite strand? 4. Assume that a 100-bair pair DNA double helix contains 45 cytosines. How many adenines are there?
