Implementing Arithmetic and Other Analytic Operations By Transcriptional Regulation
Figure 1
Schematic of a chemical model of a gene regulated by two transcription factors.
Transcription factors A and B may irreversibly form an inert dimer, C, or they may bind individually or simultaneously to the promoter region of the gene, where they affect the transcription rate. Transcripts, T, are translated into proteins, Z. Both T and Z decay at fixed rates.
