Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells. RNA molecules are real all-rounders. They transfer the genetic information from ...

HERSHEY, PA-- Penn State College of Medicine researchers have developed a tiny package that searches for and destroys up to 80 percent of hepatitis B virus in the livers of mice. "This marks one of ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the instructions for ...

RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...

Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

A study finds that an RNA enzyme, or ribozyme, can evolve to produce complex RNAs efficiently but at the cost of synthesis accuracy. Key to the development of RNA-based life, which is thought to have ...

In the March 19 Proceedings of the National Academy of Sciences, Mohammed Kashani-Sabet and colleagues describe the use of plasmid-based ribozymes as functional genomics tools to unravel complex ...

RNA molecules are an integral part of the human body: In cells, they ensure the transfer of genetic information and regulate the activity of genes. Some even act as catalysts, allowing chemical ...

The growth and metastasis of solid tumors relies on the activities of polypeptide growth factors to recruit stromal tissue and expand the tumor mass. Pleiotrophin (PTN) is a secreted growth factor ...
