LuriaDelbrückeksperimentet
LuriaDelbrücke refers to a seminal experiment in microbial genetics performed independently by Salvador Luria and Max Delbrück in the early 1940s. Their work was crucial in demonstrating that genetic mutations in bacteria arise spontaneously and are not induced by selective pressure. This challenged the prevailing Lamarckian view of inheritance, which suggested that acquired characteristics could be passed down.
Luria and Delbrück used bacteriophages (viruses that infect bacteria) and their host bacteria, specifically Escherichia coli.
Using a technique called replica plating, they showed that the resistant bacteria were present in the original
