What enzyme system is used to avoid contamination in real-time PCR?

Question

Quizplus · Accepted Answer

The dUTP-UNG system is used for PCR contamination control by introducing dUTP instead of dTTP in the PCR reaction mix and including the enzyme uracil-N-glycosylase (UNG), which is capable of cleaving the uracil-containing DNA strands. This system is effective in preventing contamination from previous PCR products, as the UNG enzyme will degrade any contaminating amplicons during subsequent PCR cycles.
