A new study by EMBL’s Duss Group sheds light on the dynamic interactions between two essential cellular processes – transcription and translation – in bacteria.
The researchers created real-time movies capturing important interactions between the key molecular components of these processes – RNA, RNA polymerases, and ribosomes.
Understanding how these fundamental cellular mechanisms work in bacteria offers new ways to think about drug development – especially in the context of growing antimicrobial resistance.
