  • Dog SNPs and Curly Hair

    Dog SNPs and Curly Hair

    In an effort to add more real data to the DNA (genetics) unit, I added a shortened form of the HHMI activity:  “Mapping Genes to Traits in Dogs Using SNPs”   The activity on HHMI is too advanced for freshman level biology, but I thought it would be a good introduction to DNA sequences. The activity…

  • Construct a DNA Model

    Construct a DNA Model

    This simple activity asks students to cut out shapes of nucleotides, each having a phosphate, a base, and a deoxyribose sugar.  Students color each nucleotide and paste them in an anti-parallel orientation.   Worksheet has space for pasting the completed model and a few questions regarding the base-pair rule, and the composition of a nucleotide.
