Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

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 ...

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 ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...
