Only ~1% of this genome can be characterized as ‘gene’ or ‘protein coding’, which leaves 99% mainly unaccountable. Previously termed ‘Junk DNA’ (non-coding DNA is a slightly friendlier term), this 99% is becoming more and more important as […]
Presumptive Testing of Body Fluids Scenario Having an indication of what the source of a particular body fluid is at a scene can provide useful information to an investigation. It can not only assist with the subsequent recovery strategy but also build a picture of the events that lead to that fluid being present. There […]
