Alina [70]

Answer:

1. transcription of mRNA from DNA

2. small ribosomal subunit binds to mRNA

3.initiation complex formed with addition of large ribosomal subunit

4.codon recognition (non-initiating site)

5.peptide bond formation

6.translocation

7. ribosome reads a stop codon

8.polypeptide chain is released from the P site

9. ribosomal subunits dissociate

Explanation:

The translation is a process which translates the nitrogenous bases or codons in the proteins.

The process of translation requires the mRNA, tRNA and ribosome and proceeds in three stages: the initiation, elongation and the termination.

The process begins with the binding of the small subunit of the ribosome to the mRNA. The charged tRNA with a first amino acid called methionine binds the mRNA and scans the mRNA until it finds the start codon.  

After it finds the start codon, the large subunit complex binds the mRNA and form initiation complex. After this, the amino acid enters the P-site of the ribosome where elongation of peptide takes place.

The peptide then exits from the E-site and the ribosome dissociates.
