Genetic modification of plants is a controversial area of biotechnology. All such experiments in plants begin with establishing plant cells in culture. This involves de-differentiating plant cells to form plant 'stem cells'. In this experiment, students establish cell cultures of African violets from leaves. They then use plant growth regulators to encourage root growth from the cultured cells, and produce a mature plant.

Students use primers for a 300 base pair Alu insertion in chromosome 16 (PV92) to determine their own genotype. They can then compare their class results with others around the world over the internet.

When DNA is subcloned in the pUC polylinker region, β-galactosidase production is interrupted, resulting in the inability of cells to hydrolyse X-Gal. This results in the production of white colonies amongst a background of blue colonies. This experiment provides a DNA fragment together with a linear plasmid and T4 DNA ligase. Following the ligation to synthesis the recombinant plasmid, competent E. coli cells are transformed and the number of recombinant antibiotic-resistant white and blue colonies are counted. β-galactosidase activity is assayed from blue and white bacterial cells.

Infectious mononucleosis is commonly known as the 'kissing disease'. The causative agent is Epstein-Barr virus (EBV), which can be transmitted through saliva during kissing. In this experiment, students search for the presence of EBV using the ELISA reaction to detect specific viral proteins.

Suppressor genes, such as p53, are essential for cell functions. Mutations in the p53 gene can be correlated to predisposition for certain cancers. Mutations of genes can either be inherited or accumulated due to environmental insults. This experiment deals with a family pedigree determination of several generations relating to cancer formation due to p53 gene mutation.

Safe drinking water is vitally important to health. Both pathogenic and harmless bacteria can be found in the guts of mammals and birds. Testing water for every possible type of pathogenic bacteria is slow and costly. Thus, water is tested for a characteristic type of gut bacteria - the coliforms - including the familiar E. coli. Presence of coliforms is an indicator for faecal contamination. In this experiment, students test for coliforms in simulated contaminated water using colour and fluorescent reagents. They can use these same reagents to test water samples from the environment. As an extension activity, a Gram Stain test can be performed on the collected samples.

The mitochondria are thought to have evolved from a symbiotic relationship between prokaryotic and eukaryotic cells. Mitochondria have their own DNA and are only inherited via the maternal line. In this experiment, students amplify two regions of their mitochondrial DNA.

In this experiment, students purify the restriction enzyme, Eco RI. This procedure utilised an ion exchange chromatograph step for Eco RI purification. Column fractions are assayed for the enzyme using Lambda DNA and digestion products are identified by gel electrophoresis. Fractions that contain Eco RI are identified and pooled. The total and specific activities are calculated. Recommended for advanced courses.

Bovine spongiform encephalophathy (BSE), also known as Mad Cow Disease, is a neurodegenerative, fatal condition in cattle. Consuming BSE-infected beef is believed to be the cause of a similar condition in humans, Creutzfeldt-Jakob disease. In this experiment, students examine simulated PCR products from several feed mills, to determine any possible violations of the ban on including animal parts in cattle feed.

This experiment introduces a simple method to determine protein subunit molecular weights using horizontal electrophoresis. As the protein standards and 'unknowns' are prestained, the separation of proteins can be observed during electrophoresis. Included in the experiment is protein-grade agarose, which provides an alternative to the use of polyacrylamide gels.

Isolation of high molecular weight chromosomal DNA is the first step in molecular cloning since it is the source of genes in cells. This experiment provides DNA extraction LyphoCells and reagents for isolating chromosomal DNA from E. coli. After spooling from solution, the DNA can be dissolved and analysed by agarose gel electrophoresis as an optional lab extension activity.

Southern blotting is an important technique used widely in clinical genetics and research. By transferring DNA from an agarose gel onto a membrane the method allows the precise analysis and identification of DNA bands on a gel. Using this kit, students use Southern blotting to find a point mutation in the haemoglobin gene indicating Sickle Cell Anaemia.
