In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

Yale researchers have now developed a method to map and measure the structure of RNA as it develops, an advance that may help ...

The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically 73-90 nucleotides ... the genetic code into the correct amino acid sequence of the protein.
