Final answer:
The d) nucleus is made of DNA and is the storage area for all genetic information. It contains genes that carry instructions for the structure and function of the organism. These genes are organized into chromosomes.
Step-by-step explanation:
The nucleus is made of DNA and is the storage area for all genetic information. It is a membrane-enclosed organelle found in most eukaryotic cells. The genetic information, encoded in DNA in the form of genes, contains the instructions for the structure and function of the organism. These genes are organized into long strands of coiled-up DNA and proteins called chromosomes.
