Using β-thalassemia as a medical example, students explore the phenomenon of gene regulation in this hands-on kit. As students progress through the lab, they will answer why changes in the DNA sequence in front of a gene (not in the gene's coding sequence) affect how much functional protein is produced by the gene. They will also use a new plasmid in a transformation experiment that includes a gene for kanamycin resistance. They learn to utilize IPTG as a compound to turn on gene expression for certain promoters. Finally, students will successfully transform plasmid to produce green fluorescent protein (GFP). Kit includes enough materials for a class of 32 students working in 8 groups of 4, as well as 1-year access to digital resources that support 3-dimensional instruction for NGSS.
