Scientists have uncovered key new information towards understanding the crucial first step in protein synthesis, the process by which the genetic code, harbored within DNA and copied into RNA, is ...

A series of structures of the eukaryotic protein-synthesis machinery are imaged at high resolution in defined states of the elongation phase of protein synthesis. Analysis suggests that there are ...

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 at ETH Zurich recently explained the role of a molecular complex that orchestrates the production of proteins in our cells. They now show that this complex also controls the processing of ...

An international team of scientists have used advanced microscopy to image how ribosomes recruit to mRNA. Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell ...

Cryo-EM structure of the Giardia ribosome reveals a highly compact, GC-rich rRNA with eukaryotic r-proteins. (A) Structure of the Giardia ribosome with all the r-proteins colored (SSU, shades of blue ...

In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then ...

With the principles of molecular biology very much in the zeitgeist these days, we thought it would be handy to provide some sort of visual aid to help our readers understand the complex molecular ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

A so-called pathological protein long associated with Parkinson's disease has been found in a new study to trigger cells to increase protein synthesis, an event that eventually kills the subset of ...

Scientists from Uppsala University have used cryo-electron microscopy to reveal details of the protein synthesis mechanism in the parasite Giardia intestinalis, which causes diarrhoeal disease. The ...
