How will you relate nucleus with DNA?

 DNA that carries genetic information is packaged into chromosomes which in turn remain enclosed in a double membrane structure called nucleus inside a cell. DNA molecules contain necessary information for constructing and organising cells.
Thus nucleus plays a key role in determining the way how the cell will develop and which form it will assume at maturity.

The nucleus is the "control center" of the cell. It tells the cell how to function and chromosome development. Chromosomes contain the genetic or hereditary instructions. Chromosomes are both composed ofnucleic acidsandprotein. The nucleic acid in protein is called deoxyribonucleic acid (DNA). DNA is stored in the Nucleus. It is not allowed to leave, for it to be used it must be copied. Short single stranded copies of one of the two DNA strands in the nucleus are made from ribonucleic acid (RNA). these copies represent detailed messages that can be transported out of the nucleus.
