2 Steps in DNA Analysis - Future Science
https://www.future-science.com/doi/pdf/10.2144/05391TN01?download=true
Once forensic scientists obtain a sample, they extract the DNA from cells in bodily fluids or tissues and copy it. They then separate the copied markers using a process known as capillary electrophoresis. This enables them to identify distinct markers and the number of repeats for different markers in each allele.
