Which of the following is the term for the dense area of DNA, RNA, and proteins inside the nucleus?
- centriole
- nucleolus
- chloroplast
- nuclear envelope

Which of the following BEST describes the nuclear envelope?
- The two-layer membrane that regulates what enters and exits the nucleus.
- The dense area of the nucleus where ribosome assembly begins.
- The area of the nucleus where chromatin condense to form chromosomes.
- The area of the nucleus where proteins are packaged for transport.
The nuclear envelope plays an important role for the nucleus. It contains the hereditary information (DNA) for the cell and controls what materials can interact with the DNA.
