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 opposite end of the folded structure, which is the 3' end of the tRNA, binds to its corresponding amino acid at an attachment site that is also three nucleotides long, invariably CCA.

In reality, there is much more to the RNA story. However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a ...

Pseudouridine is an isomer of uracil, meaning it has the same chemical formula but a different structure. It is often referred to as the "fifth nucleotide" due to its abundance in RNA. Pseudouridine ...

synaptic structure, and memory. LIU and his team shed light on the crucial role of glutamate tRNA fragments in brain aging and Alzheimer's disease, offering new insights for delaying cognitive ...
