The present invention provides a method of determining whether cytosine residues present at a predetermined positions within a singl strand of a double stranded DNA of known sequence are methylated as well as compounds for carrying out this method. The present invention also provides a process of producing a derivative of a double-stranded DNA comprising contacting the double-stranded DNA with a CpG methyltransferase and an S-adenosylmethionine analog.
本发明提供了一种确定已知序列的双链DNA中单链的特定位置是否存在甲基化的方法,以及用于执行该方法的化合物。本发明还提供了一种生产双链DNA衍
生物的过程,包括将双链DNA与CpG甲基转移酶和S-
腺苷甲
硫氨酸类似物接触。
