An electric voltage can be used to propel DNA molecules through a channel a few nanometers deep, or to stop them in their tracks. In a strong electric field the molecules judder along the channel, ...
Chemists in Japan report development of the world's first DNA molecule made almost entirely of artificial parts. The finding could lead to improvements in gene therapy, futuristic nano- ...
... .com) -- First, Cornell researchers created DNA "bar codes" -- strands of the genetic material ... fluorescing. Now, they have created new DNA molecules that can detect pathogens and deliver drugs to cells ...
Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers from Uppsala University in Sweden have now demonstrated ...

RNA polymerase moves along the DNA molecule, copying its sequence of letters into ribonucleic acid. A protein called Rho binds to the newly-synthesised RNA a blocks the polymerase, preventing it from ...
... time, researchers at Delft University of Technology have witnessed the spontaneous repair of damage to DNA molecules in real time. They observed this at the level of a single DNA molecule. Insight ...
... observing the Brownian motion of the spheres provides measurements of the electrical charges of the DNA molecules. These measurements can in turn be used to interrogate millions of DNA sequences at a ...
... to catch and straighten a DNA strand with excellent precision and care.
"When a DNA molecule is manipulated and straightened by microhooks and bobbins, the gene location can be determined easily with ...
... , along with his colleagues has designed a series of flexible, single-stranded DNA molecules, called single-stranded DNA tiles. Each single-stranded tile is exactly 42 bases long and ...
