Beskrivelse: 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.

Beskrivelse: 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.

Beskrivelse: 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.

Beskrivelse: Observer forskjellene mellom pattedyrcelletyper og hvordan disse cellene fungerer. Celler festes på objektglass og elevene farger cellene på objektglasset for å se de morfologiske egenskapene til celletypene. Disse cellene er svært trygge for klasseromsbruk.

Beskrivelse: 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 <i>E. coli</i> 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.

Beskrivelse: In this experiment, transformed cells take up a plasmid containing the Green Fluorescent Protein (GFP) gene. The GFP gene was isolated from the jellyfish <i>Aequorea victoria</i>. Transformed colonies expressing the GFP protein are visibly green in normal light but will fluoresce brightly when exposed to longwave UV light.

Beskrivelse: 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.

Beskrivelse: Drinking water is routinely tested for contamination. If a screening tests positive, more sophisticated tests are required. One such test uses PCR in multiplex format. In this experiment, students test for the presence of three separate, classroom-safe organisms in a water sample using a single PCR reaction.

Beskrivelse: 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.

Beskrivelse: 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.
