Questions for Discussion: Molecular Level of Genetics

  • Why do you think DNA exists as a double helix, versus some other shape like a highly folded protein or a linear, single-stranded fatty acid?
  • In eukaryotic cells, DNA is "trapped" inside two organelles. What are they? Do you think this is simply a biological coincidence, or might there be some benefit to cells that keep their DNA inside these structures?
  • What is a codon? Do all codons code for amino acids?
  • How can mutations occur during DNA replication? Can all genetic mutations be passed along from parents to offspring?
