DNA constraints control structure of attached macromolecules

...elevant folded and misfolded RNAs. They could also hook the DNA constraints to other molecules, including non-biological macromolecules, to control their folding. Importantly, the process of manipulating macromolecules with DNA constraints can be either reversible or irreversible, depending on which chem...

Cats' indifference towards sugar explained

...ncluding, of course, sweet. Two different proteins hook together to make each sweet receptor. According to Brand, Xia Li (lead author of the study), and their coauthors, cats do not produce one of the proteins, because the gene that codes for it is a pseudogene and is not functional. It is this lack of a ...

Biotechnology's newest chemical tool

...sauskas said, it could then be used as a molecular hook to fish out all molecules that would naturally be methylated in the cell. "There is no comparable way for global analysis of the methylation targets in the cell," Klimasauskas observed. DNA is not the only molecule that is naturally methylated in th...

Life and death in the hippocampus: what young neurons need to survive

...oung neuron to successfully jump into the fray and hook up with other cells. In a study published in a forthcoming issue of Nature, researchers in the lab of Fred H. Gage, Ph.D., a professor in the Gene Expression Laboratory and the Vi and John Adler Chair for Research on Age-Related Neurodegenerative ...

Gene discovery opens door to tackling disease

...College of Medicine in Texas. "When we baited our hook and went fishing in the breast cancer gene library we came up with SLIRP, much to our surprise, as this gene had not been characterised during the mapping of the human genome," said Professor Leedman. "What's exciting is that SLIRP has the potential...

UF scientists discover new genus of frogmouth bird in Solomon Islands

...s mouth; but their beak also sports a small, sharp hook more like an owl’s. Steadman said their beaks are like no other bird’s in the world. They eat insects, rodents, small birds ?and yes, even frogs. For perspective on the scale of evolutionary difference between genera, consider that modern humans and ...

HIV protein enlisted to help kill cancer cells

...ut it can move massive molecules. You could almost hook TAT up to a train, and TAT would drag it inside a cell. So we've taken advantage of this ability." In an article published online in January 2007 in the Annals of Surgical Oncology, the researchers describe using TAT to pull a protein called Bim in...

Navigable nanotransport

...nto little, two-dimensional "patches" that in turn hook on to other patches. Once they reach a certain size, the patches bend around and close off to form hollow spheres, which can then be filled with guest molecules. The size of the spheres is very uniform and depends largely on the solvent in which the ...
