Solution

The correct option is A Transcription
Transcription is the conversion of DNA into RNA.
On the gene that is to be transcribed, there are 3 regions i.e promoter, terminator, and RNA sequence. In prokaryites, all these processes are highly enzyme mediated and regulated because there is no clear division in between the nucleus and the cells therefore al this takes place in the cytoplasm itself. This result in zero post-transcriptional processes.

So, the correct option is 'Transcription'
