Describe The Structure Of A Nucleotide
Pg. 287 #1,3,4
1. Describe the structure of a nucleotide. A nucleotide is a sugar molecule that has 3 parts including a simple sugar, a phosphate group and a nitrogenous base. Nucleotides join together forming long chains, with the phosphate group of nucleotide bonding to the deoxyribose sugar of an adjacent nucleotide. 3. Explain why the structure of a DNA molecule is often described as a zipper. The structure of a DNA molecule is often described as a zipper because it is made of tow chains of nucleotides held together by nitrogenous bases. Just like the teeth of a zipper hold the two sides of the zipper together, the nitrogenous bases of the nucleotides hold the two strands of DNA together. 4. How does DNA hold information?
