Universal Gates: A universal gate is a gate which can implement any Boolean function with the out need to use any other gate type.
The NAND and NOR gates are universal gates.
In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.
In fact, an AND gate is typically implemented as a NAND gate followed by an inverter, not the other way around!! Likewise, an OR gate is typically implemented as a NOR gate followed by an inverter, not the other way around!!
