Edward H. Egelman 据美国弗吉尼亚大学(University of Virginia简称UVA)2022年8月2日提供的消息,在DNA中,科学家们找到了制造可以改变技术的超导体的解决方案(In DNA, scientists find solution to building superconductor that could transform technology)。 弗吉尼亚大学医学院(University of Virginia School of Medicine...
A quasi-one-dimensional organic semiconductor, hepta(p-phenylene vinylene) (HPV), was incorporated into a DNA tensegrity triangle motif using a covalent strategy. 3D arrays were self-assembled from an HPV-DNA pseudo-rhombohedron edge by rational design and characterized by X-ray diffraction. ...

Topoisomerase II binds to DNA and breaks the double strand at the same time. Two Tyr OH forms covalent bonds with 5'-P at the incision. By changing the conformation of the enzyme, the double strand passes through the incision and then re binds. The result is the introduction of negative ...
Electrophilic Affibodies Forming Covalent Bonds to Protein Targets Antibody affinity limits sensitivity of detection in many areas of biology and medicine. High affinity usually depends on achieving the optimal combination... L Holm,P Moody,M Howarth - 《Journal of Biological Chemistry》 被引量: 49...

Figure 2. Nitrogenous bases within DNA are categorized into the two-ringed purines adenine and guanine and the single-ringed pyrimidines cytosine and thymine. Thymine is unique to DNA. Individual nucleoside triphosphates combine with each other by covalent bonds known as 5ʹ-3ʹphosphodiester bon...
3.3.3 Outline how DNA nucleotides are linked together by covalent bonds into a single strand. Below is a diagram showing how nucleotides are linked to one another to form a strand. A covalent bond forms between the sugar of one nucleotide and thephosphategroup of another nucleotide. ...
To be efficient, the functionalization process must provide covalent DNA probe grafting, which is both localized and selective. On the one hand, it should take into account the global morphology and geometrical configuration of the sensing area represented by both the NW and its immediate ...
