Which set of the following events occurs during the elongation step of translation?
- Attachment of mRNA with the smaller subunit of ribosome
- Loading of correct aminoacyl-tRNA into the A site
- Formation of a peptide bond between the amino acyl-tRNA in the A site and the peptide chain that is attached to the peptidyl-tRNA in the P site
- Dissociation of the ribosomal subunits
- Translocation of peptidyl-tRNA from the A site to the P site of the ribosome
- P, Q and R
- P, Q and T
- Q, R and T
- R, S and T
