Presentation Transcript

  1. spooled DNA! gene chromosomes chromatin double helix

  2. 1953 Wilkins Franklin Watson Crick

  3. Nucleotides are the monomer of nucleic acids This component varies

  4. nucleotide The chain of nucleotides creates a nucleic acid, a polymer

  5. sugar phosphate base pairs covalent bond H-bond N-base

  6. DNA has 4 nucleotides purines pyrimidines

  7. The base pair rule makes the two helices complementary Adenine bonds to Thymine Cytosine bonds to Guanine

  8. DNA is replicated when cells reproduce (mitosis, meiosis) • each old strand acts as a template for a new one • the two stands each contain half of the original Thus replication is semi-conservative http://www.wiley.com/college/pratt/0471393878/student/animations/dna_replication/

  9. RNA is a nucleic acid with a slightly different structure Single helix Ribose sugar vs deoxyribose of DNA * uracil pairs with adenine during RNA synthesis

  10. Function of each differs, but are complementary RNA rewrites and interprets the code multiple types of RNA DNA segments of the sequence - genes - code for proteins
