Which of These Would Be Most Useful in Building a Genetic

Question

Which of these would be most useful in building a genetic circuit for memory storage?
A) miRNA
B) promoter
C) toggle switch
D) GFP
E) ssDNA binding protein

Accepted Answer

A toggle switch would be most useful in building a genetic circuit for memory storage because it allows for the stable maintenance of two states (on/off) even after the initial stimulus is removed, mimicking the binary nature of memory storage in the brain. The other options listed could all be components of a genetic circuit, but they do not specifically address the need for stable memory storage.
