We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

LIFE ON EARTH may have originated with DNA's cousin RNA, but how the modern world evolved from the RNA world is still mostly unknown. Now, in a new study published last week in the journal Nature, ...

New research published in the journal Cell reveals that scientists have managed to extract RNA, the molecule that translates ...

NIMS, in collaboration with Nagoya University, Gifu University, and the University of Adelaide, has developed a method for simultaneously imaging DNA and RNA inside cells using harmless infrared to ...
