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.
