Please answer the attached question. Please.... . .. . . . . .. .......

For PCR you requiredNTP which stands for deoxynucleoside triphosphate( like deATP, de CTP, deTTP, deGTP), Taq polymerase extracted from Thermus aquaticusbacteria, Mg2+ as it actsas a cofactor and is a catalyzer inPCR. That means, higher concentrations of Mg2+ increases higher productivity of Taq polymerase.
so what you dont require is dUTP, DNA polymerase of primates
