Characteristics of putative G-quadruplex-forming sequences in the P. falciparum 3D7 genome

Var-associated and non-var-associated groups of PQSs were scored for the four characteristics predicted to be G4-stabilizing: the table shows the number of PQSs in each group showing each characteristic. Differences between the scores for the two groups were assessed by Fisher’s exact test (2-tailed)
