Title: Bacterial cells
Post by: jalamoushi on November 01, 2012, 06:09:37 pm
Quick question- where does transcription take place in a bacterial cell??
Or does transcription not take place at all in a bacterial cell because bacterial cells contain plasmids that are self replicating?

just in cytosol. they need mRNA too, cause they need proteins. but dont have a nucleus

Transcription is involved in protein synthesis, not DNA replication - and all bacteria would need to synthesise proteins. And yeah, it would occur in the cytosol, bacteria have no membrane bound organelles.

Just ribosomes that I can remember, for the purpose of making protein

they don't have any membrane bound organelles but they have ribosomes which aren't membrane bound..like saheh said to make proteins.

Thank you! I think the last minute exam nerves are starting to get to my head.
