As we discussed in the previous lecture, the first step is the initiation process. And in this process, our mRNA molecule that codes for the protein finds the small subunit of the ribosome, and they find each other with the help of protein factors, protein molecules known as initiation factors. So once our small subunit Binds to the mRNA molecule, the small subunit then moves along the mRNA molecule until it locates a specific nucleotide sequence on the mRNA known as the star codon. So the star codon is the nucleotide sequence aug, where a is the atom nucleotide, u is the uracil nucleotide, and g is the guanine or the guanosine nucleotide. Now, once our small subunit finds the star codon, it basically signals a tRNA molecule to go out and find the appropriate amino acid, which is the methionine amino acid. The tRNA then binds to our amino acid, and we form the amino acid tRNA complex.
