complementary base pairs Learning Goal Describe the double helix of DNA DNA Ratio of Bases Scientists determined that adenine is paired 11 with thymine guanine is paired 11 with cytosine . Section 8.2: The Structure of DNA. 1. Objectives. SWBAT describe the interaction o the four nucleotides that make up DNA.. SWBAT describe the three-dimensional structure of DNA.. 2. Vocabulary – Section 8.2. 3.3.1: Outline DNA nucleotide structure in terms of sugar (deoxyribose), base. and phosphate.. 3.3.2: State the names of the four bases in DNA.. 3.3.3: Outline how DNA nucleotides are linked together by covalent bonds. Are we done yet?. Answer: Almost.. What do we need DNA for?. DNA is the genetic material which . organises. all cell processes.. DNA is a code which contains all the information to build proteins to make different cells perform different functions.. nd. 2015. Molecular genetics. Reminder: My name is Ms. M! (M for .

The nucleic acids DNA & RNA are polymers of nucleotides.. DNA differs from RNA in the # of strands normally present, the base composition & type of pentose.. THINK ABOUT IT. The DNA molecule must somehow specify how to assemble proteins, which are needed to regulate the various functions of each cell.. What kind of structure could serve this purpose without varying from cell to cell?. p. 26. 10/6. Monomer = Nucleotide. Polymer = Nucleic acid. Phosphate. Sugar (deoxyribose). Nitrogenous Base. DNA!!.
