Watson and Crick have been given credit for discovering the three dimensional‚ double helix model of DNA. They got the idea for the double helix shape from a woman named Rosalind Franklin‚ who saw the double helix shape from a picture she took of an x-ray. Frederick Griffith discovered that bacteria can change form and function through transformation. Bacteriophages are a form of a bacterial virus. Viruses act as parasites and can cause many different diseases. Erwin Chargaff figured out that units

3/1/11 1. Describe the three parts of a nucleotide and how they bond to form a nucleotide. The three parts of a necleotide are a carbon sugar‚ a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds. 2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent and hydrogen are as follows
