Describe various components of a nucleus in a eukaryotic cell?
Nucleus of eukaryotic cells contain DNA in the form of chromosomes, nucleoskeleton, nucleolus, nuclear membrane. DNA in the chromosomes carry genes and control the regulation of cell's activity, integrity of genome and gene expression. Nucleoskeleton also called as nuclear lamina is a network which gives mechanical support to the nucleus. Nuclear membrane separates the nuclear content from the cytoplasm and contain pores through which transport of materials takes place. Nucleolus is a dense membrane-bound structure present inside the nucleus and is involved in the synthesis of ribosomal RNAs and assembly of ribosomes.
