So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

Only recently has the ribosome -- one of the oldest molecular machines in evolutionary terms -- been recognized as an active regulator of gene expression at the level of protein biosynthesis.

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ...

The Steps of Protein Synthesis In prokaryotes like bacteria, transcription and translation can occur simultaneously in the ...

HHMI scientists and their colleagues discover a new mechanism of protein synthesis. Ribosomes are the cell’s molecular machines, responsible for translating genetic information in messenger RNA into ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...

That would seem to be a big enough job for one class of enzymes—and when protein-based life began, it was. But as organisms became more complex, AARSs picked up additional domains that allow them to ...

This evolutionary conservation highlights the fundamental role of tRNA in the essential process of protein synthesis. The basic structure and function of tRNAs have remained largely unchanged over ...

Chemists from HSE University and the Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences (INEOS RAS) have developed a new method for synthesising amides, essential ...
