Assertion: nucleic acid's structure | /r/HasProperty | stabilized by hydrogen bonds
Facets:
Source sentences:
text: The secondary structure of RNA is stabilized by Hydrogen bonds, intrastrand pairing of the bases (AU, GC) oftentimes resulting in structures such as hairpin loops.
text: These structures are stabilized by hydrogen bonding between the edges of the bases and chelation of a metal ion in the centre of each four-base unit.
text: RNA is nucleic acid, and its single-stranded, helical structure is constructed by nucleotides of nitrogenous bases, ribose sugar, and phosphate group; the bases are adenine, guanine, cytosine, and uracil, for which, 1’ nitrogen of pyrimidine base and 9’ nitrogen of purines base are bonded to 1’carbon of pentose sugar by glycosidic bond; base pairs of adenine and uracil and of cytosine and guanine are bonded by hydrogen bonds; the ribose is a pentose sugar of carbon numbered from 1’ to 5’ and has a hydroxyl group on the 2’ carbon; the 3’ and 5’ carbons of ribose sugar are bonded to phosphate group by phosphodiester bond; more importantly, the structure is of A-form geometry, which is constructed as of vast and thin major groove and of flat and broad minor groove, the structure can fold on itself to form secondary structure, such as tRNA and rRNA, and the secondary structure that are stabilized by hydrogen bonds, domains of loops, and metal ions, such as Mg 2+, form specific tertiary form.
