Why does the translation process could not occur in the absent of small sub-unit of ribosome?
Termination stage of translation can’t take place, codon cannot be recognize

Elongation stage of translation, codon cannot be recognize
Initiation stage of transcription can’t take place/start codon cannot be recognize
