The basic PCR mutagenesis system involves the use of two primary PCR reactions to produce two overlapping DNA fragments, both bearing the same mutation in the overlap region; this technique is thus termed overlap extension PCR .

Many species of macroparasites cannot complete their life cycles without the presence of at least two different host species

Definitive host - Exhibit sexual reproduction 

Intermediate hosts – Nonreproducing
