The key to life at the atomic level
... The answer was provided at the beginning of the 1960s. Scientists realized that the genetic message is copied to a RNA molecule (figure 3). They called it messenger RNA (mRNA). mRNA moves outside the nucleus and is caught by the ribosome, which uses mRNA as a blueprint for producing proteins. When ...
