Implementation of cascade logic gates and majority logic gate on a simple and universal molecular platform. The interesting point, of course, is that the final truth table -- which was generated from the schematic containing two NOT gates, two 2-input AND gates, and one 2-input OR gate is identical to the original truth table we created at the start of this exercise (had it turned out to be different, we'd really be in trouble). Hence, you don’t have to juggle between too many menus to get desired output. George, Harpreet Singh. The different types of basic logic gates are as follows: AND gate, OR gate, NOT gate, NAND gate, NOR gate, XOR (EXOR) gate and XNOR (EXNOR) gate.
