This addition involves formation of a covalent bond called the ‘phosphodiester ... The sugar-phosphate chains form the backbone of the ladder-like DNA structure and these base pairs form the ...

What is a covalent ... bond and can be either inter- or intramolecular. Hydrogen bonds are responsible for the lattice structure of frozen water, for example, and for joining the two strands of ...

A covalent bond between the aptamer and the target causes semi-permanent drug action. Plus, serum resistance of a DNA-type (B: this work) or peptide-type covalent aptamer (our previous work ...

The researchers have exploited the fact that thymidine bases in close proximity will form strong covalent bonds between each other when exposed to ultraviolet light. By designing DNA strands to ...

Although drugs that make covalent bonds with their biological targets are as old as the pharmaceutical industry, intentionally designing molecules that make such bonds is relatively new.

Chemistry students the world over are familiar with covalent ... hydrogen bond, the spacing between those energy levels would decrease as the atom climbed further up the energy ladder.

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus ...
