Tag: Start codon

In nearly all biological organisms, the process of translation cannot begin without a specific initiator signal. This signal tells the cellular machinery where to begin reading the genetic code, and a specific amino acid starts protein synthesis in response to that signal.

Over 90% of eukaryotic proteins begin with the amino acid methionine, which initiates the intricate process of protein synthesis, also known as translation. This crucial step, starting with a special initiator tRNA, ensures the correct reading frame for building functional proteins and is a fundamental aspect of molecular biology.
