摘    要:近年来,随着各种基因组计划的相继完成,发现在各种生物体单核苷酸链水平上存在着A≌T,G≌C的数量关系,但从几千个至十几万个碱基的范围来看,A≠T,G≠C。从数学上可以证明,如果DNA双链之间碱基的突变率一致,则A≌T,G≌C成立,但很多实验表明,双链之间的突变率并不一致,因此这个问题的解决仍有赖于数理科学和生物学的进一步结合。 Abstract:With more and more genome have been completely sequenced,scientists find the Partial Rule 2(PR2) in entire single strand that A≌T,G≌C.But from the scope of thousands to hundreds of thousand bases,A≠T,G≠C.Form the view of math,if the mutational rate of one strand is equal to others,it could be proved that A≌T,G≌C,but from the view of experience,that premise doesn't exist,so the solution of the problem needs the deeply combination of biology and math.

Abstract:With more and more genome have been completely sequenced, scientists find the Partial Rule 2 (PR2) in entire single strand that A approximately equal to T, G approximately equal to C. But from the scope of thousands to hundreds of thousand bases, A not = T, G not = C. From the view of math, if the mutational rate of one strand is equal to others, it could be proved that A approximately equal to T, G approximately equal to C, but from the view of experience, that premise doesn't exist, so the solution of the problem needs the deeply combination of biology and math.
