Characteristics of Nucleus

Following are some of the general characteristics of a cell’s nucleus;

• It is typically the cell organelle present in almost every cell.
• The nucleus is covered by a double layer of membrane called the nuclear envelope.
• The cytoplasm and the nucleus’s contents are separated by the nuclear membrane.
• The chromosomes of the cell are present within the nucleus.
• The chromosomes, which contain DNA, supply the genetic information that is necessary for the synthesis of various cell components as well as for the generation of life.
• The presence of nuclear pores on the envelope of the nucleus facilitates the movement of substances between the nucleus and the cytoplasm.

The nucleus (plural: nuclei) is a double-membraned organelle that is found only in eukaryotic cells. The name nucleus comes from a Latin term that means “nut kernel.” The nucleus was discovered by Robert Brown in 1831. It is the first cell organelle that was discovered.

The nucleus is responsible for containing the genetic material that holds the key to regulating all sorts of cellular activities. The presence and absence of the nucleus is one of the important characteristics that differentiate between the two main types of cells.
