Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole ...

The diagram illustrates the key stages of protein synthesis in a eukaryotic cell. It begins with transcription to produce pre-mRNA in the nucleus (1), followed by post-transcriptional modification (2) ...

A multi-enzyme platform is developed for sequence-unconstrained traceless protein synthesis and modification with either synthetic peptides or recombinant proteins, according to a new study out of ...

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 ...

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

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 ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...
