If I remove Arduino's Atmega328 IC and build the same circuitry on the breadboard by using 16MHz crystal and other components (that we can use to make arduino uno on breadboard), will it work as same as before? P.S. I have already uploaded the sketch.

what if I remove ATmega328 from Arduino UNO R3?

Yes.
Buy some extra controllers for projects like this.
