Insights into the geometry of genetic coding

When proteins are produced in cells based on the "genetic code" of codons, there is a precise process under which molecules called transfer RNA (tRNA) bind to specific amino acids and then transport them to cellular factories ...

Researchers explain mechanism that helps viruses spread

In an article published in the scientific journal Nature, a University of Colorado School of Medicine researcher and colleagues explain how RNA molecules found in certain viruses mimic the shape of other molecules as part ...

New Study Brings Scientists Closer to the Origin of RNA

(Phys.org) —One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 ...

Nanopore opens new cellular doorway for drug transport

A living cell is built with barriers to keep things out – and researchers are constantly trying to find ways to smuggle molecules in.‬ ‪Professor Giovanni Maglia (Biochemistry, Molecular and Structural Biology, KU Leuven) ...

New analysis shows how proteins shift into working mode

In an advance that will help scientists design and engineer proteins, a team including researchers from SLAC and Stanford has found a way to identify how protein molecules flex into specific atomic arrangements required to ...

Fly study finds two new drivers of RNA editing

RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates ...

Molecular monkey arranges X-chromosome activation

X chromosomes are very special genetic material. They differ in number between men and women. To achieve equality between sexes, one out of two X chromosomes in women is silenced. In flies, the opposite happens: in male flies, ...

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 ...
