当时只能证明rna可以切割和连接磷酸二酯键。

At that time, it had only been demonstrated that RNA could cleave or ligate phosphodiester bonds.

近年来，人类在研究磷酸二酯键水解断裂的化学模拟方面已经取得了很大进展。

In recent years, a great progress has been made in chemical mimic for the hydrolytic cleavage of phosphodiester bond by using bioinorganic methods.
