Biochemists uphold law of physics (w/ Video)

Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules—specifically, a protein ...

Decoding mystery sequences involved in gene regulation

Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...

Research sheds light on M.O. of unusual RNA molecules

(Phys.org) —The genes that code for proteins—more than 20,000 in total—make up only about 1 percent of the complete human genome. That entire thing—not just the genes, but also genetic junk and all the rest—is coiled ...

Study reveals key step in protein synthesis

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded researchers. Now, for the first ...

DNA gridlock: Cells undo glitches to prevent mutations

Roughly six feet of DNA are packed into every human cell, so it is not surprising that our genetic material occasionally folds into odd shapes such as hairpins, crosses and clover leafs. But these structures can block the ...

Unique method creates correct mirror image of molecule

Many molecules have a right and a left form, just like shoes. In pharmaceuticals, it is important that the correct form of the molecule is used. Researchers at the University of Gothenburg, Sweden, have been able to produce ...
