It contains chromosomes and is rich in DNA.
Controlling gene expression, and DNA replication are the major functions of the nucleus.
The nucleolus is a sub-organelle found in the nucleus, without a limiting membrane surrounding it.
It does not contain chromosomes, but it is rich in RNA.
The main functions of the nucleolus are ribosome synthesis, and assembling signal recognition particles.
