    The translation of mRNA begins with the formation of a complex on the mRNA (Figure 4). First, three initiation factor proteins (known as IF1, IF2, and IF3) bind to the small subunit of the ribosome.

    This preinitiation complex and a methionine-carrying tRNA then bind to the mRNA, near the AUG start codon, forming the initiation complex.

    When translation begins, the small subunit of the ribosome and an initiator tRNA molecule assemble on the mRNA transcript.

  • What is mrna

    • The small subunit of the ribosome has three binding sites: an amino acid site (A), a polypeptide site (P), and an exit site (E). The initiator tRNA molecule carrying the amino acid methionine binds to the AUG start codon of the mRNA transcript at the ribosome’s P site where it will become the first amino acid incorporated into the growing polypeptide chain.

    Here, the initiator tRNA molecule is shown binding after the small ribosomal subunit has assembled on the mRNA; the order in which this occurs is unique to prokaryotic cells. In eukaryotes, the free initiator tRNA
