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.
This is the machine that actually reads the DNA code and makes the RNA. Transcription factors that promote gene expression are called activators. Figure 1 shows transcription factors and RNA polymerase (RNAP) making an mRNA copy of the DNA. Interestingly, transcription factors can also prevent the transcription of a gene.
