-
Hume II used bloodstain evidence from a crime scene. Important because this is how dna was collected.
-
French Royal Academy of Medicine showed work of blood stain deteching, which is important because its dna being analyised in the medical field.
-
hematin crystals were created by Teichman to also use towards dna. Important because this is how dna showed any evidence.
-
The "Antozone" test was invented to test blood and peroxide together. Important because this was a way of analzing the dna.
-
Schönbein found a technique which tells the prsence of blood, even when it has been washed. IMportant because this a way of deteching blood stains or blood stains that were once on something.
-
Ernst Heinrich Häckel discovers heredity info comes from the nucleus cell. Important because its generic info of the dna.
-
"Nuclein" is isolated from white cells, also now known as DNA, by Miescher. Important because this is how dna is deteched.
