Question: The two strands in a molecule of DNA are held together by ___. (a) peptide bonds (b) covalent bonds (c) hydrogen bonds (d) ionic bonds. Base pairing in DNA: Watson-Crick base pairs (guanine-cytosine and adenine-thymine) allo...
What covalent bonds in sulfamic acid and water molecules must have been broken to form the anion of 1. Ba(NH2SO3)2 2. BaSO4 3.Ba(NH2)2 What bonds, if any, must have been broken? Show in pictures th When pla...
4b, c. To probe the folding order of the domains, we selected molecules based on their conformation in one domain and examined the conformation of the other domain (Fig. 4d). Molecules found in the refolded conformation of the NTD (EBG) between 0.1 and 0.5 M GuHCl also exhibited a ...
In the process of water freezing, a relatively long-lived hydrogen-bonded network is generated between water molecules. For the liquid-solid phase transition, from the perspective of dynamics, the decrease in temperature leads to slower molecular motion and lower kinetic energy. When the kinetic ...
Spiropyran, a well known class of acid-sensitive molecules, is composed of indoline and chromene moieties by the connection of chiral carbon centre [23]. It mainly exists in two isoforms of closed spiropyran (SP) and open merocyanine (MC), both feature widely divergent physical/chemical propertie...

Complex 2 is built up by 1D ∞1{[Zn(phen)(H2O)](C5H 6O4)2/2} linear chains and hydrogen bonded H2O molecules. The Zn atoms are coordinated by two N atoms of one phen ligand and three O atoms of one H2O molecule and two glutarato ligands to form slightly elongated trigonal bi...
It may thus be considered that the PEO-TDE surfactant molecules were coated onto the Si substrate and oriented normally to the Si surface; i.e., the hydroxyl polar head group (–OH) of PEO-TDE was anchored to the Si surface, while its alkyl chains protruded outwards, similar to the ...
