• We built a universal, single-gene logic gate, in our case a NOR gate (Fig. 1a).
• Our NOR gates are genomically integrated into yeast cells (Fig. 1c).
• The output stage of the NOR gate is a gRNA transcript, flanked by self-cleaving ribozymes (RGR).
• The output of each circuit was made observable by having the last NOR gate drive the expression of GFP.
• Circuit module for implementing the NOR gate.
• This was used to simulate the logistic map and a NOR gate.
• Furthermore, the NOR gate developed by Murali et al.
• We first model the NOR gates, then we use those models to construct the RSFF model.
• Now that we have a model for the NOR gates we can derive the model of the RSFF.
• The NOR Gate inverts the output of the OR Gate.
• Figure2 shows static observations of the NOR gate.
• A NOR gate (“not OR gate”) is a logic gate that produces a high output (1) only if all its inputs are false, and low output (0) otherwise.
• Hence the NOR gate is the inverse of an OR gate, and its circuit is produced by connecting an OR gate to a NOT gate.
• A NOT gate followed by an OR gate makes a NOR gate.
• A NOR gate is also referred to as a universal gate.
• This is made by joining the inputs of a NOR gate.
• An OR gate followed by a NOT gate in a cascade is called a NOR gate.
• From the logic circuit of the NOR gate, the output can be expressed by the equation shown below.
• So, we can also form all the basic gates using the NOR gate.
• The output state of the NOR gate will be high only when all of the inputs are low.
• The NOR gate is also classified into three types based on the input it takes.
• The NOR gate can be cascaded together to form any number of individual inputs.
• The ANSI symbol for the NOR gate is a standard OR gate with an inversion bubble connected.
• The diagrams above show the construction of a 2-input NOR gate using NMOS logic circuitry.
• The diagram below shows a 2-input NOR gate using CMOS technology.
• The NOR gate has the property of functional completeness, which it shares with the NAND gate.
• An OR gate is made by inverting the output of a NOR gate.
• Therefore, an AND gate is made by inverting the inputs of a NOR gate.
• An XNOR gate is made by connecting four NOR gates as shown below.
• \displaystyle (A+{\overline {B}})\cdot ({\overline {A}}+B)} , noting from de Morgan's Law that a NOR gate is an inverted-input AND gate.
• Like the NAND gate seen in the last section, the NOR gate can also be classed as a “Universal” type gate.
