Figure Lengend Snippet: Schematic representation of M. pneumoniae M129 P1 gene and its four gene fragments; P1-I, P1-II, P1-III and P1-IV. Each bar represents the position of UGA codons that codes for tryptophan. To express these fragments, UGA codons were modified to UGG. Fragments were amplified using a set of forward (F) and reverse primers (R).
