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 ...

The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...

In cells transfer RNA (tRNA) translates genetic information from the encoding messenger RNA (mRNA) for protein synthesis. New results from ultrafast spectroscopy and in-depth theoretical calculations ...

Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and ...

In all living organisms, the biomolecule transfer RNA (tRNA) plays a fundamental role in protein production. tRNAs are generated from precursor molecules in several steps. The enzyme tRNA splicing ...

In 1965, Cornell biochemist Robert Holley deciphered the 77 nucleotide sequence of transfer RNA. Three years later, Holley was awarded the Nobel Prize for this work, but already the race to determine ...

Many viruses have genomes made of RNA. In human cells, messenger RNA (mRNA) molecules act as intermediates; cellular machinery copies a DNA sequence into mRNA so that it can then be translated into a ...

There are different kinds of ribonucleic acids that play essential roles in many aspects of molecular biology, including the creation of proteins from gene sequences in DNA. One type of ribonucleic ...
