她惊奇的发现,RNA 双链在接近修饰位点的位置发生了解链,无法以 Hoogsteen 配对形式保持聚合。 “在 DNA 分子中,这种修饰(甲基化)是一种损伤,它可以通过碱基旋转形成 Hoogsteen 碱基对被轻而易举地吸收。而同样的修饰会严重地扰乱 R...
from the DNA to the ribosomes, where the information is used to make proteins. RNA and DNA use complementary coding where base pairs match up, similar to how the strands of DNA bind to form a double helix.
He found that 4 and 5 were unstable middle ware of RNA Initons, and explored its complement and 2's complement by a digital logic way of distincted to bio-chemical way. The author distincted that weak alkalic class of HCO3-, O-, CH3- and NH2-, to a weak acid class of Na+, K+...

While DNA is double-stranded, forming a double helix shape, RNA is single-stranded, and its chains are significantly shorter than DNA chains (a few thousand base pairs at most, compared to millions of DNA base pairs). RNA’s single-strand structure allows it to form complex three-dimensional...

they block base-pairing and induce local duplex melting in RNA. These observations provide a mechanism for disrupting RNA structure through post-tranional modifications. The different propensities to form Hoogsteen base pairs in B-DNA and A-RNA may help cells meet the opposing requirements of mainta...
The assay described here can be more generally applied to detect other topoisomerases complexes, as well as other types of DNA-protein crosslinks. Briefly, cells are lysed using a solution containing a chaotropic salt, which allows for rapid extraction of nucleic acids (DNA and RNA). DNA is ...
对于转录偶联NER(TC-NER),RNA聚合酶遇到无法解旋的DNA,就会停下,然后启动NER修复; 对于全局基因组NER(GG-NER),XPC可以探查DNA的扭曲构象来识别DNA损伤,而与具体损伤类型无关。 因此,XPC识别损伤的类型非常广泛,包括无碱基位点(AP)和某些异常碱基,只要破坏了经典的Watson-Crick双螺旋就可以[8][9]。
RNA may be may be copurified with gDNA, and the addition of RNase to the elution buffer ensures the removal of the vast majority of contaminating RNA. This chemistry can be adapted to either paramagnetic particles (PMPs), like Promega silica-coated MagneSil® PMPs, or silica membrane ...
