Opis: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Opis: When bacteria are used to make medicinally useful proteins by transformation, the protein of interest must be separated from all of the other cellular proteins. In this experiment, the unique fluorescent properties of GFP and BFP are used as an assay during their purification from an <i>E. coli</i> extract. The column fractions containing GFP or BFP are identified by fluorescence and then purified. As an optional activity, purified protein fractions can be separated by SDS polyacrylamide gel electrophoresis (SDS-PAGE) to estimate the purity and size of the GFP and BFP proteins.

Opis: Four experimental modules are combined into one experiment to provide a comprehensive biotechnology exploration focusing on the green fluorescent protein (GFP). Bacterial cells are transformed to express the GFP. The transformed cells are then grown and the GFP purified by column chromatography. Finally, the purity of the protein fractions are analysed by SDS polyacrylamide electrophoresis.

Opis: In this PCR experiment, students make billions of copies of a small amount of DNA in only 90 minutes. They just need to mix template DNA and primers with PCR beads that contain all of the other components required to carry out a PCR reaction. Students see the increasing amounts of DNA for themselves, taking samples every few cycles and analysing them on a DNA gel.

Opis: The second assay used to confirm a positive HIV ELISA result is the Western blot. Using this kit, students separate protein samples from hypothetical patients on agarose gels. The proteins are then transferred to a membrane and simulated HIV proteins are detected.

Opis: In DNA fingerprinting, variable number tandem repeats (VNTR) are used to identify individuals. Using this kit, students type themselves at the D1S80 locus on chromosome 1. This region contains between 14 and 40 copies of a 16 base pair repeat.

Opis: The three most frequently used restriction enzymes are Eco RI, Bam HI and Hind III. Each enzyme catalyses cleavage at the defined base sequence. All enzymes are lyophilised and contain 1500 units. One unit is defined as the amount of enzyme required to digest 1,0 µg of lambda DNA in 60 minutes at 37 °C in a total reaction mixture of 50 µl.

Opis: DNA mapping is a common procedure used to determine the location of genes. In this experiment, DNA markers and pre-digested plasmid DNA fragments are mapped using agarose gel electrophoresis.

Opis: This experiment helps teach students about restriction enzyme digests in the context of forensic science. Students cut DNA with restriction enzymes and then compare the banding pattern of the crime scene DNA versus that of two suspects using agarose gel electrophoresis.
