Stars are born inside clouds of gas and dust which are predominantly molecular in composition. The chemistry and physics of these molecules are important contrib- utors to the overall evolution of the parent clouds and on the formation of the stellar systems. We review the methods and techniques...
Formation of metastable {ital dt}{mu} molecules in {ital t}{mu}(2{ital s})-{ital D}{sub 2} collisions The formation process of metastable {ital dt}{mu} molecules in {ital D}{sub 2}-{ital T}{sub 2} mixtures is investigated. The {ital dt}{mu} molecule exhibit... J Wallenius...
To deepen understanding of the polymer elongation mechanism, we conducted a meticulous examination of the fructooligosaccharide profile evolution during the levan synthesis. As a result, the formation of primary and secondary intermediates series in different reaction stages was observed. The origin of ...
No. of protein atoms 7946 No. of non-protein atoms 247 No. of water molecules 615 Average -B-factor (Å2) 25.54 Ramachandran analysis Favored (%) 95.96 Allowed (%) 3.94 Disallowed (%) 0.1 PDB code 4ud8 Chain A of the model consists of residues Ser-27 to Gly-532. Chain B starts...
(1) describes the identification, in the promoter region of the organizer-specific gene goosecoid , of two distinct growth factor responsive elements that are required for the regulation of this gene both in vitro and in vivo . This is an important finding since it provides molecular evidence ...
As in normal meiosis, after DNA replication Spo11p induces multiple genome-wide double-stranded breaks (DSBs) that lead to the formation of intermediate recombinant molecules24. These molecules are then resolved upon the re-entering of the mitotic cell cycle, resulting in dispersed LOH tracts that...
molecules yields H3+, i.e., H2 + H2+ → H3+ + H. It is worth noting here that the proton abstraction by H2observed in methanol resembles the Hogness and Lunn reaction leading to the formation of H3+. In addition to its formation through femtosecond laser excitation, H3+...
