Function of Nucleus

The nucleus is responsible for containing the genetic material that regulates the hereditary characteristics of the cell. Other than that there are some important functions that the nucleus performs;

• The nucleus regulates the cell’s growth and reproduction as it contains the cell’s genetic information.
• Proteins would move across the nucleus with the help of a signal called a nuclear export signal.
• The genetic makeup of a cell is contained in the nucleus.
• In addition to serving as a DNA storage space, it also serves as the location of various significant cellular functions.
• In the nucleus, one’s DNA can be duplicated first and foremost by the process of DNA replication.
• Cell division begins with creating two exact replicas of the parent DNA, with each new cell receiving a unique set of DNA and nucleus.
• Secondly, transcription takes place in the nucleus. Different RNA types are produced by transcription from DNA.
• When cell division occurs the chromatin fibers are arranged into chromosomes inside the nucleus that can be observed.
• The synthesis of ribosomes also occurs inside the nucleus.

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.
