Can you tell the difference between a traditional plant and one that has been genetically modified? Do their seeds look different? Do they germinate and develop differently? Do they respond differently to their environment? Learn the answer to these and other questions concerning the topical subject of genetically modified plants. Your students will gain key insight into this controversial, emerging science as they compare traditional soybeans with seeds that have been genetically modified to withstand the effects of Roundup (TM) herbicide.
Using four different samples of WARD’S Simulated Blood, the class will determine each unknown sample’s blood type and Rh factor, examine the risk of Rh incompatibilities, and view red and white “blood cells” under the microscope in complete safety. It includes four simulated blood types (A, B, AB, O), two anti-sera (A, B), Rh antisera, a teacher’s guide, and student copymaster. Enough materials for 12 setups are included.
This intermediate-level 8-station kit introduces the concepts of PCR and DNA fingerprinting and simulates the use of DNA in forensic investigations. The "DNA" fingerprints of 2 suspects are compared at 2 loci for a match with evidence DNA after being electrophoresed in agarose gels and stained with CarolinaBLU(tm) stain. Also buy the kit's predigested DNA in bulk by the mL; minimum order is 1 mL. Order bulk DNA 2 weeks prior to desired ship date. For 8 groups of students.
It's easy to teach students the basics of DNA gel electrophoresis and analysis with this classic AP(r) Biology lab. Using convenient pre-cut fragments, students electrophorese, stain, and visualize uncut lambda DNA (control) and DNA predigested with EcoRI and HindIII (standard molecular weight marker). They then determine the sizes of the DNA fragments. Materials are sufficient for 4 or 8 teams of students or 8 separate instructor demonstrations.
Can you imagine a medical practice where the focus is helping the body to heal itself using stem cells, or where diseased organs are replaced by an organ grown from a patient's own cells? These ideas might seem like science fiction, but current regenerative medicine research is nearing a point where these procedures are close to implementation. Some scientists suggest that the practice will become a reality within five to ten years.
