A "Buffer Gate" in Synthetic Biology Can Best Be Described

Question

A "buffer gate" in synthetic biology can best be described as
A) a single repressor molecule (R1) that prevents the production of an output molecule (Pr1).
B) alternate input molecules (I1 or I2) that drive the production of alternative proteins (Prn).
C) a single input inducer molecule (I1) that leads to the production of a single product (Pr1).
D) kill switches.
E) a potent DNA-damaging toxin.

Accepted Answer

A buffer gate has a single input molecule (inducer) that triggers the production of a single output molecule. The purpose of the buffer gate is to ensure that the level of output remains constant despite fluctuations in the level of input. It acts as a buffer or a stabilizer for the system.
