DNT

One of the mechanisms causing gene mutation might be to change of the Taq DNA polymerase conformation. It interfers with the enzyme-substrate-dNTP binding site and further causes replication mismatch.

这一实验结果也说明了稀土是一种诱变剂，引起基因突变的机制之一可能是改变taq DNA聚合酶的立体构象，干扰了酶与底物dNTP结合位点，从而引起复制错配。

[ METHOD] Different levels on concentration of DNA template, primer, dNTP mixture and Taq DNA polymerase and annealing temperature were set in this experimentation. All factor influence for SRAP-PCR in peanut genome was investigated.

【方法】对模板DNA、引物、dNTP mixture、taq DNA聚合酶浓度及退火温度设置不同梯度，研究各因素对PCR结果的影响；

Concentration of primer, magnesium chloride, dNTP, template DNA, Taq DNA polymerase and annealing temperature in PCR and the quantity of PCR product and endonuclease and digesting time in digestion process affect the profiles of the whole experiment.

PCR反应体系中不同模板含量、引物浓度、taq DNA聚合酶用量、dNTP浓度、Mg2+浓度、退火温度和酶切体系中PCR产物量、内切酶量、酶切时间等对反应结果均有不同程度的影响。

Moreover, the concentrations of Mg2+, dNTP and Taq DNA polymerase in allele-specific PCR were higher than that in conventional PCR.

在等位基因特异PCR中，Mg2+、dNTP及taq DNA聚合酶的用量均大于普通PCR。

In order to establish the optimized SSR detection system, the concentrations of DNA, Mg~ ( 2+), Taq DNA polymerase, dNTPs, and the annealing temperature were optimized for SSR-PCR reaction.

为建立适宜的SSR反应体系，对影响SSR-PCR扩增的模板DNA浓度、Mg~（2+）的用量、taq DNA聚合酶浓度、dNTPs浓度、退火温度等因素进行了优化。
