Genetically Modified Food—
Student Laboratory Kit
By: The Flinn Staff
Your students will gain insight into genetically modified food as they compare the growth of traditional soybean seeds with seeds that have been genetically modified to withstand the effects of a widely used herbicide. What are the implications for our food supply? What are the advantages to the soybean farmer? This hands-on activity will provide firsthand experience with transgenic crops and serve as a basis to do further study and research on this timely topic. Includes detailed student and instructor materials, soybean seeds, pots, soil, herbicide and all other necessary materials.
Complete for 30 students working in pairs.
Transcription and Gene Expression
in Bacteria—Student Laboratory Kit
By: The Flinn Staff
Explore the effect of temperature on gene expression in bacteria, and learn how genes are turned on and off in response to environmental conditions! Student lab kit provides a simple method to improve student understanding of the factors that control gene expression. Students incubate the nonpathogenic bacteria Serratia marcescens on nutrient agar at two different temperatures. The bacteria may be red, pink, white or colorless depending on whether the red pigment prodigiosin is produced. Several specific enzymes are required for the synthesis of this pigment. Although the bacteria will grow over a wide temperature range, the genes for these enzymes are only transcribed below a certain temperature. Includes reproducible student handouts and detialed Instructor’s Notes.
Complete for 30 students working in pairs. S. marcescens culture must be ordered separately.
Sordaria Genetics—
Student Laboratory Kit
By: The Flinn Staff
Students prepare cross plates and cross wild-type and mutant strains of Sordaria fimicola in this advanced genetics laboratory. Daily observa- tion of the growing culture provides an opportunity to observe the life cycle of a member of the fungal kingdom. During meiosis, crossing over occurs in some of the asci. By counting the number of crossed ascospores versus uncrossed ascospores, it is possible to determine the distance between the gene for spore color and the centromere of the chromosome of interest. Students collect, prepare, count and calculate from their own cross plates.
Complete for 30 students working in pairs. S. fimicola wild-type and tan mutant strains are available separately. An autoclave, stereoscopes, light microscopes and Bunsen burners are required.
