Question

Quizplus · Accepted Answer

The correct sequence for the beginning of translation starts with mRNA binding to the ribosome's small subunit (3), followed by the tRNA with methionine binding to the mRNA and the large ribosomal subunit joining (2). Then, another tRNA molecule enters the A site and binds to the mRNA codon (1), and finally, an amino acid from a tRNA in the P site is attached to the tRNA in the A site (4).
