Paul Zamecnik and collaborators discovered tRNA (transfer RNA) [2]. This groundbreaking discovery identified tRNA as a key component in the process of protein synthesis.
Understanding tRNA's Role
- Adaptor Molecule: tRNA acts as a literal "adaptor" [3], translating the genetic code from messenger RNA (mRNA) into the amino acid sequences that make up proteins.
- First Non-Coding RNA: Remarkably, tRNA was the first non-coding RNA to be discovered.
Significance of the Discovery
The discovery of tRNA was crucial for understanding the mechanism of protein synthesis, which is essential for all living organisms. By identifying this "adaptor" molecule, Zamecnik and his team revealed a critical step in how genetic information is translated into the proteins that carry out various functions within cells.
