In Prokaryotes, in context of m-RNA which of the following is not true?
1 Transcription and translation takes place in same compartment
2 Post-transcriptional modifications are required
3 Translation occurs after completion of transcription only
4 2 and 3
Explanation:
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
