    High School Lab
    In this DNA lab, students extract DNA from their cheek cells to learn about the structure of DNA and DNA replication. The lab has students think about why they were using each reagent and how that relates to the polarity of lipids. Students answer questions regarding DNA base pairing and it relates to the central dogma (DNA - Proteins - Traits).

    High School Test
    With this DNA structure quiz, students’ knowledge of the structure of DNA is assessed. Topics include double helix, nucleotide monomers, DNA polymers, nucleic acids biomolecules, DNA replication, complementary strands and base pairing, deoxyribose sugar and phosphate backbone, and nitrogen bases, adenine, guanine, cytosine, thymine.

    High School Lab
    In this DNA modeling lab, students build a paper model of the double helix. Students label the DNA molecule with the four DNA nucleotides and practice nitrogen base paring. At the end of class, students can attach all the models and twist and coil them to simulate super coiling.

DNA Replication


DNA Concepts

  • Nucleic Acids - DNA, RNA.
  • Shape - double helix, 5’ OH group and 3’ phosphate group.
  • DNA Nucleotide - deoxyribose sugar, phosphate group, dna nitrogen base, hydrogen bonds.
  • DNA Nitrogen Bases - adenine, thiamine, guanine, cytosine, purines, pyrimidines.
  • RNA Nucleotide - ribose sugar, phosphate group, rna nitrogen bases.
  • RNA Nitrogen Bases - adenine, uracil, guanine, cytosine.
  • Semi-Conservative Replication - complementarity, leading strand, lagging strand, Okazaki fragments, replication fork, 5’ to 3’.
  • DNA Replication Enzymes - DNA helicase, DNA polymerase, RNA primer, DNA ligase.
  • Gene Mutations - point mutations, base-pair substitution, silent mutations, transition mutation, transversion mutations, missense mutations, nonsense mutations, frameshift mutations, insertion, deletion, revertant.
  • Chromosomal Mutations - deletion, duplication, inversion, translocation.
  • Genetic Disorders - nondisjunction, down syndrome or trisomy 21, trisomy X or XXX syndrome, Klinefelter’s syndrome or XXY, Edwards Syndrome or trisomy 13.
  • Prokaryotes - operon, promoter, operator, repressor protein, lac operon.
  • Negative Gene Regulation - repressible operons, corepressors, inducible operons, inducer.
  • Positive Gene Regulation - activator, allosteric site.
  • Eukaryotes - modify chromatin, control elements, steroid hormones, regulatory proteins, TATA box, gene dosage, gene amplification.
