What are forward and reverse mutations?

What are mutations ?

The following table provides the set of values, of V and I, obtained for a given diode. Assuming the characteristics to be nearly linear, over this range, calculate the forward and reverse bias resistance of the given diode.

Define mutation.

In the figure the emitter forward bias or reverse bias?

Define gene mutation

What is junction diode ? How is depletion layer formed ? Draw its forward and reverse bias characteristics by showing biasing of diodes ?

In the following diagram, is the junction diode forward biased or reverse biased?
