Is it possible to build an AND gate from a NOT gate?
Here is one way to use inverters (NOT) to yield the AND function:

If both inputs are high, then the inputs to the second inverters are both low and the output is high. If either input goes low, one of the second inverters (or both if both inputs are low) get an input high and pulls the output low.
