At the start of the initiation phase of translation, the ribosome attaches to the mRNA strand and finds the beginning of the genetic message, called the start codon (Figure 4). This codon is ...

This preinitiation complex and a methionine-carrying tRNA then bind to the mRNA, near the AUG start codon, forming the initiation complex. Table 1 shows the N-terminal sequences of proteins in ...

During initiation, the small ribosomal subunit binds to the 5' end of the mRNA and scans along the mRNA until it reaches the start codon (AUG), which codes for the amino acid methionine. The large ...
