High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

Students create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

Students investigate DNA strands. They study the sequence to determine if it is DNA or RNA and write the mRNA nucleotide sequence. After stringing the beads together to create the mRNA sequence they translate it into an amino acid...

Seventh graders explore general structure of and natural changes that occur in DNA strands, and discuss concept of genetic engineering by creating small portion of strawberry chromosome with three genes, modeling naturally occurring...

Learners examine the structure and functions of DNA. They discover the effects radon has on one's DNA and how it leads to cancer. They discuss why DNA is so important to us.

Students construct various virus models using Fruit loops and Alphabits to represent nucleotides and molecules. They constructs capsomeres using shoes as the capsomeres and discuss various viruses.

Students explore the process of translation. They determine the correct sequencing and present their strands to the class. In addition, they compare normal red blood cells to sickle cells and complete discussion questions.

Students compare mitosis and meiosis with regard to chromosome number in parent cells versus daughter cells, types of cells produced, total number of cells produced, and the number of divisions. In groups, identify and differentiate the...
