dna molecules

(Weizmann Institute of Science) Scientists at the Weizmann Institute of Science demonstrate that a mathematical concept called recursion can be applied to constructing flawless synthetic DNA molecules.

The ideal molecules are created in successive rounds in which faultless segments are lifted from longer, error-containing DNA strands and assembled anew.

For the first time, researchers 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 into this type of repair mechanism is essential as errors in this process can lead to the development of cancerous cells.

(Delft University of Technology) For the first 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 into this type of repair mechanism is essential as errors in this process can lead to the development of cancerous cells.

Researchers from the Kavli Institute of Nanoscience Delft publish this in the leading scientific journal Molecular Cell.

Utilizing a technique that combines low temperature measurements and theoretical calculations, scientists have revealed for the first time the electronic structure of single DNA molecules.

The knowledge of the electronic properties of DNA is an important issue in many scientific areas from biochemistry to nanotechnology -- for example in the study of DNA damage by ultraviolet radiation that may cause the generation of free radicals and genetic mutations.

Utilizing a technique that combines low temperature measurements and theoretical calculations, Hebrew University of Jerusalem scientists and others have revealed for the first time the electronic structure of single DNA molecules
