Step-by-step explanation:
Translation is the process of the formation of the protein product from the RNA molecule. Th different enzymes and transcription factors are required for the process of translation.
The three process of translation are initiation, elongation and termination. The elongation factors are required to add the further amino acids one by the one to the growing amino acid and continues the process of elongation of the translation.
