_________ D2. State the names of the four bases in DNA _____

 _________ D3. Outline how DNA nucleotides are linked together by covalent bonds into a single strand. ____

_________ D4. Explain how a DNA double helix is formed using complementary base pairing and hydrogen bonds. _____

___________D5. Draw and label a simple diagram of the molecular structure of DNA. _____

___________D6. Explain DNA replication in terms
