Detailed Solution

The nuclear lamina is a netlike array of protein filaments made up of lamin proteins that provide mechanical support to the nucleus by maintaining the shape of the nucleus. However, it is not bounded by ribosomes, as ribosomes are present on the outer membrane of the nucleus while nuclear lamina is a network of intermediate filaments that is present on the nuclear side of the inner membrane of the nucleus. Therefore, the incorrect statement is, "It is bounded by ribosomes."
