Students analyse their own DNA in guest lecture

Applied Science students at Rochdale Sixth Form College with renowned biologist John Schollar, from Reading University

Applied Science students at Rochdale Sixth Form College welcomed renowned biologist John Schollar, from Reading University, to find out more about DNA analysis as part of their studies.

Using state of the art equipment, usually reserved for university students and scientists, John was able to give 40 A Level students a unique insight into cutting edge techniques behind DNA profiling and genetic fingerprinting.

Students were able to build up a profile of their own DNA by swirling liquid around their mouths and spitting the contents into a cup. The liquid, which contained their cheek cells, was amplified using a Polymerase Chain Reaction machine.

The sample was analysed using a method called gel electrophoresis. Forensic scientists use this process to help identify crime suspects and it is also used in paternity tests and to help diagnose genetic diseases.

Laura Harrison, Applied Sciences teacher, said: “Applied Science is all about making science ‘real’ and linking to the world of work. It is important that students receive a varied experience in their studies and bringing in industry experts adds an extra dimension to how they approach the work that they need to cover.”
