Coupled Transcription-Translation in Bacteria — NEET Biology

🔥 Predicted for NEET 2027
📖 NCERT Source

In bacteria, since the mRNA does not require any processing to become active, and also since transcription and translation take place in the same compartment (there is no separation of cytosol and nucleus in bacteria), many times the translation can begin much before the mRNA is fully transcribed. Consequently, the transcription and translation can be coupled in bacteria.
