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 ...

Scientists look at the base pairs that compose the "rungs" of the DNA ladder to determine a genome's sequence. The success of E. coli bacteria depends on their ability to multiply very rapidly by ...

DNA is the raw material of modern medicine yet is the only part of drug development not accessible at the lab bench. DNA synthesis, the first step in most biological workflows including gene synthesis ...

Illinois biochemistry professor Satish Nair and his colleagues discovered a new class of DNA-protein hybrids and determined the mechanisms by which they are formed in bacterial cells. The findings ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Researchers at ETH Zurich recently explained the role of a molecular complex that orchestrates the production of proteins in our cells. They now show that this complex also controls the processing of ...
