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 ...

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 ...

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 ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

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 ...

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 ...
