A large ribosomal subunit bonds to the initiation complex. The codon adjacent to the initiation codon bonds to its complementary anticodon, which is part of a free tRNA. The two amino acids still attached to their tRNAs align. With the help of rRNA, amino acids form peptide bonds. Then, the first tRNA is released.
During translation, mRNA is sandwiched between the small and large subunits, and the ribosome catalyzes the formation of a peptide bond between the two amino acids that are contained in the rRNA. A ribosome also has three binding sites called A, P, and E. The A site in the ribosome binds to an aminoacyl-tRNA (a tRNA bound to an amino acid).
