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 ...

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 ...

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 ...

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 ...
