1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar.
b) Deoxyribose sugar is the sugar that is found in a nucleotide.
c) The nitrogen-containing base is the nucleotide component that contains nitrogen.
d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine.
2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and the deoxyribose sugar.
b) The nitrogen-containing base(s) and hydrogen bond(s) make up the rungs of the "ladder" model of DNA.
c) The phosphate and the deoxyribose sugar are the parts of the nucleotide(s) that make up the sides (backbone) of the "ladder"
