Year 11 GTAC Excursion

At GTAC (Gene Technology Access Centre in Parkville), the Year 11 Biology students worked with several scientists to undertake an inquiry into prenatal and predictive genetic testing, to explore how each test works and identify when different tests are used and why. They explored chromosome abnormalities through a modelling activity and performed a Guthrie test to diagnose if babies have Phenylketonuria (PKU). Students also performed a DNA digest and gel electrophoresis to determine the PKU allele status for a family and used their results to construct a family tree.
