The Nucleus is the site where Gene transcription occurs i.e. DNA is converted into RNA/mRNA.
This enables Gene translation i.e. The mRNA is decoded into Ribosomes in the cytoplasm or on the endoplasmic reticulum which synthesise Proteins.
Together this is called the process of Gene expression
The enzymes produced by the nucleus controls cell metabolism and
The DNA within the nucleus provide the blueprint for replication
