VCE Biology Students Hands-on Experience in Genetic Engineering

Last week, our Year 12 Biology students delved into the fascinating world of genetic modification during their science incursion. The incursion offered students a hands-on experience in genetic engineering, focusing on the insertion of the Green Fluorescent Protein (GFP) gene into bacteria.

Students meticulously genetically modified bacteria by incorporating the GFP gene, a technique commonly employed in biological research. This process not only enhanced their understanding of genetic manipulation but also provided valuable insights into the practical applications of genetic engineering in various fields.

Furthermore, students were introduced to the intricacies of DNA profiling through gel electrophoresis and Polymerase Chain Reaction (PCR). These techniques are vital tools in forensic science, medical diagnostics and evolutionary biology. Through hands-on experimentation, students gained proficiency in DNA analysis, honing their laboratory skills while unravelling the mysteries of genetic code.

The incursion served as a catalyst for scientific exploration. By actively engaging in cutting-edge experiments, students not only expanded their scientific knowledge but also cultivated critical thinking and problem-solving abilities essential for their academic and professional pursuits.

Thank you to Mrs Karinda Hogan and Mr Mark Thompson who assisted our Year 12 Biologists.

STUDENT REFLECTIONS

“On Friday, we performed pracs in 3/4 Biology that would form part of a SAC in the coming weeks. The pracs that we did involved Polymerase Chain Reaction (PCR), gel electrophoresis and transformation.

It was really exciting to be able to use the school’s new PCR machine as CMC is one of the only schools in the region to have one. Our first prac. involved DNA profiling to solve a crime. This process involved amplifying DNA and profiling it using gel electrophoresis. Our second prac. was about transforming DNA plasmids to make them produce commercial amounts of proteins. It was really fun to be able to do pracs like this and work with others in the class.” (Caitlyn Brew)

“During our class we completed experiments on Polymerase Chain Reaction, gel electrophoresis and transformation. We got to use our brand-new PCR machine. It was amazing to be able to use it and see how it actually works. I really enjoyed being able to see the different stages that occur during PCR on the screen as the machine was doing each step. We then used that DNA in gel electrophoresis machines and were able to see amazing banding patterns from the DNA that went through PCR.” (Elise Long)
