Mutations and intron polymorphisms in voltage-gated sodium channel genes of different geographic populations of Culex pipiens pallens/Culex pipiens quinquefasciatus in China

Table 6 Sequence characteristics of downstream introns adjacent to the mutant gene

Base site	A, %	T, %	C, %	G, %
First base site (108 bp^a)	30.2	28.8	23.8	17.2
Second base site (110 bp^a)	26.7	28.4	22.8	22.2
Third base site (109 bp^a)	29.9	25.8	23.9	20.4
Total fragment (326 bp^a)	28.9	27.7	23.5	19.9

T represents thymine. A represents adenine. G represents guanine. C represents cytosine. % Indicates the proportion of the nucleic acid in the fragment. ^arepresents the fragment length (bp), which is the average fragment length of 28 geographical populations
