The hydrolytic stability of the diastereomeric isomers of ApA was compared and the results show that heterochiral ApAs are more rapidly hydrolyzed than homochiral ApAs at low temperatures, suggesting that hydrolytic selection in cold environments in conjunction with selective polymerization may have been effective in enriching the homochirality of RNA.
ApA的二构象异构体的水解稳定性进行了比较,结果显示在低温下,异向旋光的ApA的水解速率比同向旋光的ApA更快,这表明在寒冷环境中的水解选择作用结合选择性聚合可能有效促进了RNA的同向旋光丰富性。
