The nuclear envelope is the membrane that basically is the nucleus of a cell. It holds all the cell's DNA, and keeps it separate from everything else. It's like a mini cell, inside a cell. Think of it sort of like a wiffle ball. It's covered in tiny pores that allow small things, like RNA, to pass through it. At the same time, however, it keeps the chromosomes in, and does not allow larger proteins or organelles to pass through.
