Question

what is the primary function of the nucleolus within the nucleus? *
to assemble ribosomes, which are essential for protein synthesis.
to modify and package proteins for secretion.
to store the cells genetic material.
to synthesize lipids for the cell membrane.

ribosomes are crucial for protein synthesis. where in the cell are ribosomes typically found carrying out this function?
free in the cytoplasm and attached to the endoplasmic reticulum.
primarily within the mitochondria.
exclusively within the nucleus.
only attached to the golgi apparatus.

Explanation:

The nucleolus assembles ribosomes which are key for protein - synthesis. Ribosomes are found free in the cytoplasm and attached to the endoplasmic reticulum where they carry out protein - synthesis.

Answer:

1. To assemble ribosomes, which are essential for protein synthesis.
2. Free in the cytoplasm and attached to the endoplasmic reticulum.
