The function of nucleus in the cell are :
- It carries genes and helps in inheritance of of character from parents to progeny.
- It also the metabolic activity of the cells
- it is refered as the brain of the cell

The nucleus is a membrane-enclosed organelle found in eukaryotic cells.
The function of a nucleus is to control all activities of a cell. It controls gene expression and mediate the replication of DNA during the cell cycle.

The nucleus is a double membrane organelle separate from the cytoplasm that contains the majority of the genetic material in a eukaryotic cell. This genetic material is in the form of deoxyribonucleic acid (DNA), and this along with any other DNA present in a cell (e.g. in the mitochondria) make up the genome (completely set of genetic material in a cell) of an organism.
The DNA in the nucleus is double stranded and consists of genes (a specific length of DNA consisting of mononucleitides joined together by phosphodiester bonds) consisting of non coding DNA (introns, which contain short tandem repeats at specific loci) and coding DNA (exons). This coding DNA is really important as it is transcribed to produce mRNA which is complementary to the antisense strand of DNA and therefore consists of particular codons (triplets of bases). This mRNA detaches from the DNA and leaves the nucleus through a nuclear pore, entering the cytoplasm where it binds to a ribosone and is translated to produce a primary structured protein (polypeptide chain/sequence of amino acids). This process is called protein synthesis and it allows a cell to produce particular proteins depending on which genes are switched on (therefore expressed) or off which depends on the epigenetic markers on the DNA contained in the nucleus, which have been established due to the environment or developmental cues.
