Transcription in Bacteria
... If the gene transcribed encodes a protein, the result of transcription is messenger RNA (mRNA), which then will be used to create that protein via the process of translation. Alternatively, the transcribed gene may encode for either noncoding RNA genes (such as microRNA) or ribosomal RNA (rRNA) or t ...
