Figure 3. Memory encoding in computers and applied to the Central Dogma Cycle.

A. A NOR gate only produces an output when both inputs are off. B. One version of a bit (SR latch) is built from a circuit combining two NOR gates, each with two inputs and two outputs (A and B). One output of each NOR gate is one of the two inputs of the other NOR gate with Inputs A and B being the additional inputs for each gate. Output Q and its inverse, Q̄ are the outputs of each gate. 0 is considered no input and 1 is considered and input. The output behaviors of each input are dependent on the history of the other input. C. An example expressing how the Transcription Cycle can be encoded by digital logic gates to create memory and decision making. Cycles are labeled with blue fonts and electrical symbols with orange fonts. Four steps of the Transcription cycle (transcription, pre-mRNA splicing, RNA degradation, and RNA base regeneration), one step inputting to the Translation cycle in the CDC, and the Nonsense Mediated Decay (NMD) and ATP cycles from the broader CDCN are shown. The figure were generated with PowerPoint.
