    Nuclear envelop

    Explanation:

    Nuclear envelop is the double membrane structure that makes the boundary of the nucleus. It serves to protect the DNA from the toxins, wastes and other harmful substances produced during metabolic reactions of the cell occurring in cytoplasm.

    If the nuclear envelope does not protect DNA, DNA could be damaged by free radicals or toxins. A cell with damaged DNA is subjected to death.
