What exactly is the function of a nucleus in a cell?

The nucleus is the thing in the center of a cell. It doesn't have to be in the center, it could be anywhere inside the cell. The nucleus controls the cell as if it were a brain. It could tell the cell when to work and even when to die! The nucleus is the most important piece of the cell and if there is no nucleus, the cell would be doing weird and crazy things.

Nucleus is the master organelle of all living cells .It is called as the brain of the cell. All the major functions of the cell are performed under the instruction of nucleus. In animal cells it is present in the middle of the cell whereas in plant cells it is pushed towards the periphery. Nucleus contains chromatin material.The chromatin material consist of DNA which is the hereditary material of the cell.The major functions are:-1.It is involved in cell division. 2.It stores all the information that is to be transferred to the next generation.3.Assembly of ribosomes takes place in the nucleolus present inside the nucleus.4.DNA replication and transcription processes take place inside the nucleus.Transcription is the formation of mRNA. This messenger RNA then plays its role in the translation, the process of protein synthesis.Thus the information generated by nucleus governs the formation of enzymes and other proteins that carry out all the processes of body.

The nucleus contains the genetic information of the cell. it controls all the cell's functions. the dna in nucleus is necessary for division, also the nucleolus in the nucleus makes ribosomes which is necessary for protein synthesis
