When gold beads were injected into a cell to see whether or not they could get into the nucleus itwas discovered that beads bigger than 9 nm in diameter (orbigger than the size of a proteinwith a molecular weight of ~40,000) could not get intothe nucleus. Yet we know thatsome proteins larger than this can get into the nucleus. How do these larger proteinsget into the nucleus? (hint: there is more than one thingrequired to accomplish this)
