Verified step by step guidance1
Understand the role of tRNA in protein synthesis. tRNA molecules carry amino acids to the ribosome, where they are added to the growing polypeptide chain.
Learn about the initiation of translation in eukaryotes. The process begins with the assembly of the ribosome on the mRNA strand, starting at the start codon.
Identify the start codon in mRNA, which is typically AUG. This codon signals the beginning of translation and codes for the amino acid methionine.
Recognize that the tRNA carrying methionine is the first to bind to the ribosome at the start codon, initiating the process of translation.
Note that methionine is often the first amino acid incorporated into a new protein, as it is coded by the start codon AUG, which is recognized by the initiator tRNA.
