Nucleus is the large membrane organelle that contains the genetic material the form of
Multiple linear DNA molecules organized into structures called chromosomes. A nucleus
Is a group of specialized nerve cells in the brain or spinal cord. The nucleus is not always
In the middle of a cell its like in the middle of all the cytoplasm. Not all cells have nucleus.
Eukaryotic cells have an organized nucleus and you can find DNA, RNA, and Chromatin
In the nucleus of the cell.
This organelle has two major functions they are that it stores the cells hereditary material,
Or DNA, and it coordinates the cell's activities like growth, metabolism, and
reproduction. When a cell is resting not dividing the chromosomes structures called
Chromatin. Nucleus contains the nucleolus that helps to synthesize the ribosomes.
The nuclear envelope is a double-layered membrane that encloses the nucleus during
Most of the cells lifecycle. The nuclear envelope is perforated with the holes called
Nuclear pores these pores pass through the nucleus and cytoplasm. Building blocks
For building DNA and RNA are allowed in the nucleus but so as well as molecules
That provide the energy for forming genetic material.
Nucleolus is visible when cell is not dividing, it contains RNA for protein manufacture.
