This model works in units of genes per year. It is assumed that Transcription, Repair and the Food Queue are all in Gene units in spite of their having different functions. The Repair process repairs Genes per year. The Transcription process transcribes Genes per year and the Exogenous Food source adds Food in Genes needed to process it per year. Transcription proportion is in Genes (10 of them split between transcription and repair). Other variables like Damage and CpG are dimensionless.
