Intro to dna

  1. 1. Intro to DNA
  2. 2. Nucleic Acids <ul><li>Composed of carbon, oxygen, hydrogen, nitrogen, and phosphorus </li></ul><ul><li>Their structural unit, the nucleotide, is composed of N-containing base, a pentose sugar, and a phosphate group </li></ul>
  3. 3. Nucleic Acids <ul><li>Five nitrogen bases contribute to nucleotide structure – adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U) </li></ul><ul><li>Two major classes – DNA and RNA </li></ul>
  4. 4. Deoxyribonucleic Acid (DNA) <ul><li>Double-stranded helical molecule found in the nucleus of the cell </li></ul><ul><li>Replicates itself before the cell divides, ensuring genetic continuity </li></ul><ul><li>Provides instructions for protein synthesis </li></ul>
