Elongation: RNA polymerase moves along the DNA template strand, reading the nucleotide sequence and adding complementary RNA ...

As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...

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 ...

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 ...

An organism’s genome could be compared to a complex system of instructions that allows it not only to develop, but also to carry out all the activities essential to its survival. To do this, this ...

RNA plays a vital role in how our genes are expressed and how diseases develop. Yet, because RNA molecules constantly change ...

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 ...

Thomas Gingeras did not intend to upend basic ideas about how the human body works. In 2012 the geneticist, now at Cold Spring Harbor Laboratory in New York State, was one of a few hundred colleagues ...
