What is the correct order of the three steps of translation?

The correct order of the three steps of translation is Initiation, Elongation, and Termination.

During the initiation phase, the components necessary for translation are assembled at the start codon of the mRNA. This includes the ribosomal subunits, tRNA, and the mRNA itself. Initiation sets the stage for protein synthesis by ensuring that all the parts are in place and correctly aligned.

Following initiation, the elongation phase begins. In this step, the ribosome travels along the mRNA, adding amino acids to the growing polypeptide chain as dictated by the sequence of codons in the mRNA. tRNAs bring the appropriate amino acids to the ribosome, which facilitates the formation of peptide bonds between them.

Finally, the termination phase occurs when a stop codon is reached on the mRNA. This signals the end of protein synthesis, prompting the ribosome to release the newly formed polypeptide and disassemble, completing the translation process.

Understanding the sequence of these steps is essential for grasping how genetic information is translated into functional proteins, which are vital for the structure and function of cells.
