Question

Which among the following would you find in a eukaryotic nucleus?

• A. Nuclear membrane
• B. Chromatin
• C. Nucleolus
• D. All of the above

Answer 1

The correct option is D All of the above

The nucleus is a double membraned organelle containing the genetic material in a eukaryotic cell. It is the largest cell organelle in animal cells. A nucleus at rest or in a non-dividing phase shows the following parts:

• Nuclear membrane: Consists of the outer and inner membrane. It is also called the nuclear envelope.
• Nucleoplasm: It is a transparent, semi-fluid substance enveloped by the nuclear membrane. It contains the chromatin and the nucleolus.
• Nucleolus: It is a roughly spherical structure present inside the nucleus. It mainly serves as a site for ribosomal RNA synthesis.
• Chromatin: These are the thread-like structures present in a nucleus. Chromatin is a complex of DNA and proteins. Before cell division, chromatin coils and condenses to form chromosomes.
