Answer:
A) after a transcription initiation complex has been formed
Explanation:
Translation is the process of formation of protein and transcription is process of formation of RNA.
In prokaryotes, trancription and translation coupled with each other. Translation process in prokaryotic cells occurs with the formation of transcription initiation complex and follows three stages initiation, elongation and termination.
In prokaryotic cells, transcription and translation begin together because mRNA is produced in the cytoplasm in prokaryotes, the start codons of an mRNA being transcribed are available to ribosomes before the entire mRNA molecule is even made.
Hence, the correct option is A.
