Presentation Transcript

  1. => AsamNukleat • Polimercincinribofuranosida yang dihubungkanolehgugus ester fofat. • Setiapribosaterikatpadabasa. • Ribonucleic acid (RNA) • Deoxyribonucleic acid (DNA) Chapter 23

  2. => Ribonucleosides A -D-ribofuranoside bonded to a heterocyclic base at the anomeric carbon. Chapter 23

  3. Ribonucleotides Add phosphate at 5’ carbon. Chapter 23

  4. Structure of RNA => Chapter 23

  5. Structure of DNA • -D-2-deoxyribofuranose is the sugar. • Heterocyclic bases are cytosine, thymine (instead of uracil), adenine, and guanine. • Linked by phosphate ester groups to form the primary structure. => Chapter 23

  6. Base Pairings => Chapter 23

  7. => Double Helix of DNA • Two complementary polynucleotide chains are coiled into a helix. • Described by Watson and Crick, 1953. Chapter 23

  8. DNA Replication => Chapter 23

  9. Additional Nucleotides • Adenosine monophosphate (AMP), a regulatory hormone. • Nicotinamide adenine dinucleotide (NAD), a coenzyme. • Adenosine triphosphate (ATP), an energy source. => Chapter 23

  10. End of Chapter 23 Chapter 23
