(Nanowerk Spotlight) Hydrogen bond base pairing forces are essential for the mechanisms associated with DNA stability. Despite attracting great research attention, this fundamental interaction has ...
In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen bonds with cytosine (C). These base pairs are highly ...
Within the familiar double helix, complementary hydrogen-bond sequences provide all the ... that spell out these commands — individual base pairs — are not particularly robust structures ...
Table 1 Conductances calculated with DFT for hydrogen-bonded bases spanning a pair of gold electrodes ... to characterize the stiffness of hydrogen bonds in few-molecule interactions, and have ...
“There has been quite a lot of computational work looking at hydrogen bonding [and] proton transfer in DNA base pairs,” said Sam Hay, a professor of computational and theoretical chemistry at ...
The hydrogen bonds between the base pairs form the double helical structure of DNA. There is no exchange or sharing of electrons in hydrogen bonds as seen in covalent or ionic bonds. Hydrogen ...
The role of the hydrogen bonds, which have sometimes been seen as crucial to holding DNA helixes together, appears to be more to do with sorting the base pairs, so that they link together in the ...
These four molecular bases—adenine, thymine, cytosine and guanine—pair with each other using hydrogen bonds to form the foundation for a DNA strand. There are only the two base pairs—A bonds ...
"When these two bases form a hydrogen bond by accident ... so they can fit like a normal base pair and escape DNA repair mechanisms. "They're bad guys, but they pretend to be good guys to survive ...
Tokmakoff and colleagues characterized the hybrid bond by observing groups of atoms called bifluoride ions, consisting of a single hydrogen atom sandwiched between a pair of fluorine atoms ...
For DNA to be read, replicated or repaired, DNA molecules must open themselves. This happens when the cells use a catalytic protein to create a hydrophobic environment around the molecule.
