Together, the evidence was convincing. “What all of this was saying was that we were getting a totally unprecedented mechanism for ribosome-mediated protein synthesis,” Weissman says. “Every other ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).
