Study reveals how ribosomes override their blockades
Ribosomes are "protein factories" in the cells of all living things. They produce proteins based on existing genetic codes stored on special nucleic acid molecules. These molecules, also called messenger RNA (mRNA) due to ...

Research reveals novel transport mechanism for large ribonucleoproteins
The movement of genetic materials, such as RNA and ribosomes, from the nucleus to the cytoplasm is a critical component in a cell's ability to make the proteins necessary for essential biological functions. Until now, it ...

Researchers uncover new mechanistic insight into mRNA biogenesis and export
A team of EU-funded Spanish and Polish researchers have revealed the structure of a protein complex that is essential for messenger RNA (mRNA) biogenesis and export. Writing in the European Molecular Biology ...

Study of ribosome evolution challenges 'RNA World' hypothesis
In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells. And according ...

Biologists uncover a novel cellular proofreading mechanism
(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

From gene to protein: Gene expression quantification offers new insights
How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for ...

Working in concert
As cells go about the process of building new proteins, each amino acid gets delivered individually to the protein-synthesizing machinery of the ribosome by a specialized transfer RNA (tRNA) molecule. This ...

Copycat protein finds a perfect match
As proteins are synthesized during messenger RNA translation, fresh amino acids are delivered to the ribosome of the cell by nucleic acid molecules known as transfer RNAs (tRNAs). Each amino acid has a cognate ...
