Advanced UGC-NET Forensic Science Unit II drill on electrophoresis: charged-particle migration in an electric field, mobility derived from Stokes friction, low-voltage and high-voltage regimes, buffer choice (TBE, TAE, Tris-glycine-SDS), support media (paper, cellulose acetate, agarose, polyacrylamide), specialised techniques (SDS-PAGE for protein MW, native PAGE for activity, IEF for pI separation, two-dimensional PAGE for proteomics, capillary electrophoresis for STR fragments, MEKC for neutrals), and immuno-electrophoresis variants (Grabar-Williams, Laurell rocket, crossed Laurell, Ouchterlony double diffusion). Forensic applications cover blood group typing via Lattes and serum proteins, isoenzyme polymorphism (PGM, EsD), STR allele separation in DNA profiling, drug enantiomer separation, haemoglobin variant identification, semen confirmation via PSA and SVSA, and Indian context covering ICMR DNA labs and CFSL DNA divisions. Hard-band scenario questions test which support, buffer, voltage regime, or detection mode applies in a real forensic biology, DNA, or serology problem.
Questions are written and edited by the ForensicSpot team and cited from peer-reviewed forensic textbooks, official syllabi and primary case law. Each one is verified before publishing. Detailed explanations show after you submit, so the test stays a real test. See a mistake? Tell us.
