The nucleus is the control center of a cell. The nucleus controls the cell's growth and reproduction and contains the cell's DNA.Continue Reading
The nucleus of a cell contains most of that cell's genetic material. Its job is to maintain the integrity of the cell while controlling its activities. The nucleus is separated from the cytoplasm by a membrane called a nuclear envelope.This helps to protect the cell's chromosomes which is where the DNA is located.
The nucleus was first discovered by microscopist Antonie van Leeuwenhoek in the mid-1600s while he was examining the red blood cells of salmon. The nucleus was again observed in 1804 by Franz Bauer and botanist Robert Brown, who described the nucleus in great detail in 1831.Learn more about Cells
A cell that lacks a nucleus is a prokaryotic cell. Prokaryotes are unicellular organisms that also are lacking other organelles typically found in eukaryotic cells, which do have a nucleus. The structures found in a prokaryotic cell are cell membrane, cell wall, cytoplasm, DNA and ribosomes.Full Answer >
The nucleus is designed to govern and control everything that happens within the entire cell, which includes the process of cell division. The nucleus is enclosed by a protective membrane, and it consists of three components, which are the nucleoplasm, chromosomes and the nucleolus.Full Answer >
According to Reference.com, cellular organisms that do not have a distinct nucleus, such as bacteria, are called prokaryotes. They are distinct from the eukaryotes, which are the cellular organisms that contain a nucleus.Full Answer >
If the nucleus of a cell becomes damaged by a xenobiotic substance, it can prevent the cell from dividing and lead to other problems. In many cases, the damage eventually causes the death of the cell.Full Answer >
