Gold nanoparticles below a certain size limit that are injected into the cytoplasm can later be observed in the nucleus. This is explained by which of the following:

Molecules below a certain size can diffuse nonselectively through the nuclear pore complex.
There are gold-specific ion channels on the nuclear envelope.
Gold particles contain a nuclear localization signal.
The DNA requires gold to function effectively.
