Tryptophanyl-tRNA was specifically labeled at the 3' end with [3H]tryptophan and cleaved in half with RNase under denaturing conditions, and the 3' half was shown to hybridize exclusively at the 5' end of avian myeloblastosis virus RNA. The RNA-dependent DNA polymerase of avian myeloblastosis virus is capable of efficiently binding the 3' half of the primer molecule.
色氨酰 - tRNA在3'端用[³H]色氨酸进行特异性标记,并在变性条件下用核糖核酸酶切成两半,结果显示3'半段仅在禽成髓细胞瘤病毒RNA的5'端杂交。禽成髓细胞瘤病毒的RNA依赖性DNA聚合酶能够有效结合引物分子的3'半段。
