A new mechanism helps explain differences between eukaryotic and bacterial proteomes
Why do distinct species have different proteins? Is there a key that allows eukaryotic cells to produce proteins involved in multicellularity that are mostly absent in prokaryotes? These are some of the questions addressed ...

Advanced sequencing technology provides new insights into human mitochondrial diseases
The ability to translate the genetic code into proteins is an essential step in all living organisms. A cornerstone of this molecular process is the ability of transfer RNA (tRNA) molecules to couple recognition of the genetic ...

Cell mechanism regulating protein synthesis in stress conditions discovered
Genes must be expressed in precise levels and at the exact moment if the complex balance regulating cell activity is to be maintained. Messenger RNA (mRNA) conveys genetic information from DNA to ribosomes, where proteins ...
