The nucleus is bounded by what structure, which consists of two complete membranes similar in structure to the plasma membrane?
Correct Answer
nuclear membrane
Explanation
The nucleus is bounded by the nuclear membrane (also called the nuclear envelope), which consists of two complete membranes similar in structure to the plasma membrane. It is perforated by many large pores that facilitate the passage of substances — such as RNA and ribosomal subunits — in and out of the nucleus.
