The shape of nucleus is spherical..The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes.

What are chromosomes and inside What are they present
I want each and every material present in cell
chromosomes are thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

A cell nucleus is the part of the cell which contains the genetic code, the DNA. The nucleus is small and round, and it works as the cell's control center. It contains chromosomes which house the DNA. The human body contains billions of cells, most of which have a nucleus.
Within the nucleus is a structure called a nucleolus. It is made at a nucleolus organizer region (NOR), which is a chromosomal region around which the nucleolus forms. Inside the nucleolus ribosomes are made. These are exported through the nuclear pore complexes to the cytoplasm, where they are work to build proteins and sometimes become attached to the endoplasmic reticulum if they are making membrane proteins.
Coming to the outer nuclear membrane
Large molecules cannot get through the double-layer nuclear membrane: it is impermeable to them. However, nuclear pores exist. They control the movement of molecules across the membrane. The pores cross both nuclear membranes, providing a channel. The larger molecules are actively transported by carrier proteins, and there is free movement of small molecules and ions. Movement of large molecules such as proteins and RNA through the pores is required for both gene expression and the maintenance of chromosomes.
