The nucleus is a cell organelle found in eukaryotic cells. It is bound by the membrane and contains the cell’s hereditary information i.e. it contains the information that will be passed on.

Structure:

• The nucleus is surrounded by a membrane known as the nuclear membrane.

• The nuclear envelope has pores through which the RNA and proteins pass through.

• The nucleus contains DNA and RNA which form chromatin.

• When chromatin condenses, it forms chromosomes.

• There is another structure called nucleolus present inside of the nucleus.

• The nucleolus is made up of RNA and proteins.

• There is another substance present inside the nucleus. It is known as the nucleoplasm. It is a gel like substance.

Function:

• Nucleus is like the brain of the cell.

• Nucleus stores the genetic information in the form of DNA.

• It is the DNA that contains all the information regarding how the cell would work.

• The nucleus also aids in cell division.

• It is the nucleus that makes RNA which is then made into proteins.
