FRNSC 420 - EXAM 3 PRACTICE QUESTIONS AND ANSWERS (100% PASS) electrophoretic mobility shift assay (EMSA) - Answer️️ -demonstrates if a protein is bound to DNA - fragment is placed in non-denaturing polyacrylamide gel (native PAG) to keep protein associated to DNA - DNA/protein complex moves much slower in the gel due to added molecular weight (an electrophoretic mobility shift) - will appear higher in the lane compared to free DNA - migration depends on mobility of the protein; dif...

Hoofdstuk 12 behandelt het identificeren en classificeren van mutaties, met aandacht voor forward en reverse genetics. Mutagenen worden gebruikt om kunstmatige mutaties te induceren, gevolgd door mapping en het toewijzen van mutaties aan genen. Hoofdstuk 13 richt zich op het koppelen van fenotypen aan DNA-sequenties. Genetische kartering en expressieanalyse leiden tot kandidaatgenen, terwijl geavanceerde genoomsequencing directe identificatie mogelijk maakt. Kandidaatgenen worden bevestigd doo...
