On Tuesday, June 6th Rochester Secondary College hosted an incursion from the Gene Technology Access Centre (GTAC). Year 12 Biology students from Rochester, Echuca College and East Loddon P-12 participated in a practical activity in which they inserted a glow in the dark gene from a jellyfish into Escerichia coli bacteria. Genetic manipulation is part of the Unit 4 Biology course. Year 10 students from Rochester and East Loddon completed a gel electrophoresis as part of an investigation into how western populations have become more lactose tolerant over time. They have been studying genetics and evolution this semester.
