The PCR primers must not have self complementary regions as this would lead to hairpin formation within primer molecules and make then unsuitable for PCR.

#Unit 3. Fundamental Processes
Alkylating agents are chemicals that donate alkyl groups to other molecules as nitrogen mustard, and methyl and ethyl methane sulfonate (MMS and EMS).
#Id: 643
EMS causes ethylation of the bases in DNA at the 7-N and the 6-O positions of G cause G:C → A:T transitions.
#Id: 644
Alkylating agents induce all types of mutations, including transitions, transversions, frameshifts, and even chromosome aberrations.
#Id: 645
hydroxylating agent hydroxylamine (NH2OH) induces only G:C → A:T transitions not reversal.
#Id: 646
When DNA is treated with hydroxylamine, the amino group of cytosine is hydroxylated.
#Id: 647
X rays, gamma rays, and cosmic rays is ionizing radiation and ultraviolet light is nonionizing radiation.
