The structure and role of the nucleus in the life of the cell.

The nucleus is a membrane organelle of eukaryotic cells. The nucleus stores DNA information. DNA strands are packed in complex ways into chromosomes. This protects the genetic information from alteration and damage. When cell division occurs, the number of chromosomes doubles. During this period, you can easily examine the chromosomes in an ordinary light microscope. The nucleus is essential for the synthesis of proteins. Ribosomes, which directly “assemble” proteins from amino acids, receive mRNA using the cell nucleus. Therefore, the nucleus is very important in the cell.
