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

Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, ...

New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA. Every living cell transcribes DNA into RNA. This process begins when an ...

A research team at the University of Würzburg has deciphered another aspect of poxviral gene activation. The study reveals a ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...

Researchers at the Johns Hopkins Kimmel Cancer Center and Department of Radiation Oncology and Molecular Radiation Sciences uncovered a new tumor-suppressive response that could lead to novel ...
