Teach your students about gene transfer between bacterial strains. In 1 of the included strains of E. coli, the gene for antibiotic resistance for streptomycin is located on the chromosome. In the other, the gene for antibiotic resistance for ampicillin occurs as extrachromosomal plasmid DNA. Through the process of streaking the conjugated bacteria on 4 different types of antibiotic selective media, students determine which bacterial strain is the donor strain. Kit includes prepaid coupon to request perishable materials later at your convenience. Contact us or return coupon to request delivery of perishable materials.
Note: Antibiotic solutions and cultures last 1 month when refrigerated.

3-D Molecular Designs. Using these captivating models and tools, students explore proteins' primary, secondary, and tertiary structures. They learn the chemical properties of the 20 amino acid side chains using dynamic side chain models. These models still feature dual-coloring schemesa colored band at the base indicates chemical propertiesbut new embedded plastic balls show atomic structure. Since understanding the structural and chemical properties of the amino acid side chains is essential to grasping the basics of protein structure, working with the side chain models helps students comprehend protein structure. An additional protein-folding activity further deepens students' understanding as they explore the role of the side chains' properties in creating secondary structure.
