Translation: initiation. | |||
---|---|---|---|
A small ribosomal subunit binds to mRNA. An initiator tRNA, with the anticodon UAC and carrying the amino acid methionine (Met), base-pairs with the start codon AUG. | A large ribosomal subunit completes the initiation complex. The initiator tRNA is in the P site; the A site is available to the next tRNA. |
