How do you describe the structure of the nucleus of a cell?

Great Answer

Professionally Researched. (What's this?)

The nucleus of a cell is an organelle (specialized component within a cell) that is responsible for regulating gene expression. Its structure is intricate and multifunctional.

Significance

The nucleus houses DNA and controls the activities relating to protein synthesis, growth, metabolism and cell division.

Size

The nucleus is a spherical organelle that occupies approximately 10 percent of the cell's volume.

Features

The nucleus is surrounded by a double-layered nuclear envelope with pores. The pores are connected by rough endoplasmic reticulum (sac-like structure used to transport proteins). Within the nucleus, nucleoplasm suspends chromatin (condensed form of DNA) and the nucleolus.

Function

The nucleolus is a structure within the nucleus that produces ribosomes (organelle that constructs protein). The nuclear envelope separates the contents of the nucleus from the cytoplasm. The nuclear pores regulate what come into and goes out of the nucleus.

Identification

The nucleolus appears as a large dark spot within the nucleus when viewed through a microscope. This identifies the nucleus within a cell.
