  • Reinforcement:  DNA, RNA, and Sickle Cell

    Reinforcement: DNA, RNA, and Sickle Cell

    Students practice DNA and RNA by completing this simple fill-in-the-blank worksheet that focuses on vocabulary related to DNA structure and function.

  • Investigation: Sticklebacks

    Investigation: Sticklebacks

    This investigation was modified from the HHMI Stickleback Modeling activity where students examine two different forms of the the stickleback fish. One form has spines and bony armor and is found in the ocean. The other has less armor and is missing its pelvic girdle, and is found in fresh water lakes. The activity has…

  • Genetics of Sickle Cell

    Genetics of Sickle Cell

    This assignment was created for students who miss class and can be completed independently. There are sections to read with questions to answer, focusing on how DNA provides the instructions to make protein. A single base substitution in the gene that codes for hemoglobin results in sickle cell anemia. Students are walked through the process…

  • DNA, Proteins, and Sickle Cell

    DNA, Proteins, and Sickle Cell

    In this activity, students use a codon chart to compare the DNA sequence of HbA (normal hemoglobin) to HbS (sickle cell). The DNA differs in a single base, where the codon for normal hemoglobin codes for glutamine, and the mutant form codes for valine. 

  • DNA Coloring

    DNA Coloring

    In this activity, students color a DNA molecule according to directions that describe the base-pair rule and how the backbone of the molecule is composed of deoxyribose and phosphate arranged in a double helix.  In addition, students are introduced to the concept of messenger RNA and how the sequence of bases determine and amino acid chain…

  • Human Immunodeficiency Virus (HIV) Coloring

    Human Immunodeficiency Virus (HIV) Coloring

    The virus that causes AIDS (Acquired Immunodeficiency Syndrome) is called the Human Immunodeficiency Virus, commonly known as HIV. HIV is a member of the retrovirus family, which means it contains RNA as its genetic material instead of DNA. HIV coloring worksheet uses a model to understand viral transmission.  Students identify and color the major structures…
