1. STRUCTURE OF DNA AND RNA

2. REBUS PUZZLES For once in my lifeBroken PromiseWhat goes up must come down

3. STRUCTURE OF DNA AND RNA DNA: A double-stranded nucleic acid that contains all the genetic information for cell growth, division, and life functions.  Deoxyribose Nucleic Acid Target: I will be able to describe and/or diagram the structures of the DNA and RNA molecules, and contrast DNA and RNA Pg. 73

4. Nucleic Acids: macromolecules that store and transmit genetic information.  Types: DNA & RNA  Made of nucleotides.

5.  Nucleotides: molecules made of a pentose sugar, a phosphate group, and a nitrogen base.

6. Structure of DNA  Double Stranded Twisted in a double helix  Sugar-Phosphate Backbone  Sugar is Deoxyribose  Held together by Covalent bonds.

7.  4 Nitrogenous Bases – Adenine (A), Thymine (T), Cytosine (C), and Guanine (G)  Base Pairs in the middle.  A always bonds to T  C always bonds to G  Held together by hydrogen bonds.

9. Structure of RNA  Single Stranded  Sugar-Phosphate Backbone Sugar is Ribose Held together by Covalent Bonds  One Nitrogen base off of each sugar A, C, G, U (Uracil)

11. DNARNA Function Location Structure Instructions for assembling proteins Assembles (Puts together) Proteins Nucleus Cytoplasm Double Stranded Nitrogen bases = A, T, C, G Sugar = Deoxyribose Single Stranded Nitrogen bases = A, U, C, G Sugar = Ribose Summary:

12. CONTRASTING DNA AND RNA Pg. 72 Diagram the structure of DNA and RNA. - Label the sugar, phosphate, bases, bonds, and circle a nucleotide. Make a T-Chart, label one column DNA and the other RNA. Then draw a picture to show each of the differences between DNA and RNA in the notes. Use a minimum of four colors.
