Prohibiting smoking in all public housing units nationwide would save nearly $60 million annually in property destroyed by fire and cleaning up smoking related damage to public housing units.
RNA polymerase is the core enzyme in transcription which needs proteins known as transcription factors to bind to the DNA promoter. also DNA plymerase... can't remember what about it though. DNA polymerase isn't involved in DNA transcription. However, DNA polymerase IS involved in DNA REPLICATION.
Once the prokaryotic genome has been condensed, DNA topoisomerase I, DNA gyrase, and other proteins help maintain the supercoils. One of these maintenance proteins, H-NS, plays an active role in transcription by modulating the expression of the genes involved in the response to environmental stimuli.
