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 ...
While great strides have been made in exploring the world of RNA, mysteries remain—and one approach to solving them is to look at what exactly a strand of RNA is doing in a cell in real time. At a ...
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a ...
Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...
Scientists have unveiled QT45, a 45-nucleotide RNA enzyme that can copy itself and its complementary strand in icy, salty conditions resembling those on early Earth. Its small size makes spontaneous ...

The discovery of RNAi dates back to the 1990s when researchers observed unexpected gene silencing in plants and fungi. In 1998, Andrew Fire and Craig Mello published a groundbreaking study ...
