Multiple Choice

What is the functional connection between the nucleolus, nuclear pores, and the nuclear membrane?

The nuclear pores are connections between the nuclear membrane and the endoplasmic reticulum that permit ribosomes to assemble on the surface of the ER.

The nucleolus contains messenger RNA (mRNA), which crosses the nuclear envelope through the nuclear pores.

Membrane of the endoplasmic reticulum is produced in the nucleolus and leaves the nucleus through the nuclear pores.

None of the listed responses is correct.

Subunits of ribosomes are assembled in the nucleolus and pass through the nuclear membrane via the nuclear pores.

Verified step by step guidance

Understand the role of the nucleolus: The nucleolus is a region within the nucleus where ribosomal RNA (rRNA) is synthesized and combined with proteins to form ribosomal subunits.

Identify the function of nuclear pores: Nuclear pores are large protein complexes that span the nuclear envelope, allowing the transport of molecules such as RNA and ribosomal subunits between the nucleus and the cytoplasm.

Recognize the structure of the nuclear membrane: The nuclear membrane, also known as the nuclear envelope, is a double lipid bilayer that encloses the nucleus, separating it from the cytoplasm.

Connect the nucleolus to nuclear pores: Ribosomal subunits assembled in the nucleolus are transported out of the nucleus through the nuclear pores to the cytoplasm, where they participate in protein synthesis.

Summarize the functional connection: The nucleolus assembles ribosomal subunits, which then pass through the nuclear membrane via the nuclear pores, linking the nucleolus, nuclear pores, and nuclear membrane in the process of ribosome assembly and transport.
