Forensic DNA Profiling — STR / PCR / Capillary Electrophoresis

Interactive forensic DNA profiling simulator: amplify STR loci by simulated PCR (exponential doubling per cycle), separate the fragments by simulated capillary electrophoresis, read the resulting electropherogram peaks, and compare a crime-scene profile against multiple suspects locus by locus.

ControlsLocus dropdown selects which of 5 STR markers to inspect (highlights its band on the DNA helix and shows crime-scene vs suspect allele calls); suspect dropdown picks 1 of 4 candidate profiles; 'Run PCR + CE' button plays the full amplification-cycle animation then races allele fragments along the capillary to the detector, plotting electropherogram peaks live; 'New Case' regenerates the crime-scene profile and all suspects; camera orbit/zoom via drag and scroll.

Simulated PCR amplification of five STR loci followed by capillary-electrophoresis size separation, rendered live as an electropherogram, with a crime-scene profile compared against selectable suspect profiles locus by locus.

⚙ Under the hood

Amplify five STR loci with simulated PCR (real exponential doubling per cycle), separate the resulting fragments by simulated capillary electrophoresis (migration speed inversely tied to fragment size), read the electropherogram peaks, and compare a crime-scene profile against selectable suspects locus by locus.
