The proteins upon which life depends share an attribute with paper airplanes: Unless folded properly, they just wont fly. But researchers have been puzzled by how the long, linear proteins cranked out by the ribosome factories in a cell are folded into the shapes they must assume to perform their function.

The research, published in the journal Nature Structural & Molecular Biology, says a protein called shugoshin holds the answer. Also known as SGO1, this protein fits precisely into a sort of keyhole which gives the chromosome its X shape

Chromosomes are long DNA molecules that contain the genetic material of an organism but their shape has always remained a mystery.

They believe a protein called SGO1 may play a role.

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and m ...

Mitochondria are considered to be the power plants of cells and are essential for human metabolism. Dysfunction in 40 percent of mitochondrial proteins are associated with human diseases, which is why mitochondria also play an important role in medical research.

The RNA quadruple helix Roschdi and Butcher study, called a “pUG”, can wind around itself four times to create a cube shape that can affect gene silencing. In this rendering, the uridine (U) nucleotides are blue while the guanosine (G) nucleotides are green.

A new study has deciphered the mechanical code of DNA to reveal previously unknown ways in which nature encodes biological information in DNA sequence.
