In bacteria, in context of mRNA, which of the following is not true?

a. Transcription and translation takes place in different compartment.

b. Post-transcriptional modifications are required like splicing.

c. Translation occurs only after transcription.

In bacteria, the mRNA does not require any processing to become active, and also transcription and translation take place in the same compartment. Many times the translation can begin much before the mRNA is fully transcribed. Consequently, the transcription and translation can be coupled in bacteria.
