RNA editase transforms or modifies the nucleotide of pre-RNA by deaminization, and hydrolytic deaminize C6 amino group of the adenosine at the specific RNA site, changing adenosine to inosine or changing cytosine to uracil,but inosine was recognized as guanine in mRNA.

RNA编辑酶以脱氨方式使得RNA特异位点的腺嘌呤脱氨转变为次黄嘌呤，或者是特异位点的胞嘧啶变为尿嘧啶，而次黄嘌呤在碱基配对时被识别为鸟嘌呤。

Generally, B in the configuration closest cell's DNA conformation, it and the double helix model are similar. A-DNA and when RNA member double helix area as well as duplication forms the DNA-RNA hybrid molecule conformation is close. Z-DNA take the nucleotide dimer as the unit left-hand winding, its principal chain assumes the denticle the shape, therefore.

一般认为，B构型最接近细胞中的DNA构象，它与双螺旋模型非常相似。A－DNA与RNA分子中的双螺旋区以及转录时形成的DNA－RNA杂交分子构象接近。Z－DNA以核苷酸二聚体为单元左向缠绕，其主链呈锯齿形，故名。
