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 ...

This film creatively illustrates the process of protein synthesis through dance, symbolizing the assembly of amino acids into proteins. It explains how genes encode instructions for amino acid ...

The discovery of catalytic RNA transformed our understanding of life's beginnings. Clare Sansom explores how the RNA world ...

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 ...

An international team of scientists have used advanced microscopy to image how ribosomes recruit to mRNA. Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell ...
