Presentation Transcript

  1. Chapter 21 Nucleic Acids and Protein Synthesis 21.2Primary Structure of Nucleic Acids

  2. Primary Structure of Nucleic Acids In the primary structure of nucleic acids, • nucleotides are joined by phosphodiester bonds • the 3′ —OH group of the sugar in one nucleotide forms an ester bond to the phosphate group on the5′carbon of the sugar of the next nucleotide

  3. Primary Structure of Nucleic Acids (continued)

  4. Structure of Nucleic Acids A nucleic acid polymer • has a free 5′-phosphate group at one end and a free 3′—OH group at the other end • is read from the free 5′end, using the letters of the bases • segment shown here is read as: 5′—A—C—G—T—3′

  5. Example of RNA The primary structure of RNA • is a single strand of nucleotides • consists of the bases A, C, G, and U linked by 3′—5′ ester bonds between ribose and phosphate
