Structure of DNA:

DNA, or deoxyribonucleic acid, is a thread-like structure that contains the genetic information of an organism. It is composed of two long strands of nucleotides twisted into a double helix shape.

Functional parts of DNA:

- Chromatin: DNA in its loose, uncoiled form is referred to as chromatin. Chromatin allows for DNA replication, gene expression, and repair mechanisms to occur.

- Chromosome: DNA condenses into chromosomes during cell division. Each chromosome contains a single molecule of DNA that is tightly coiled and organized. Chromosomes are essential for the proper segregation of genetic material during cell division.

- Gene: Genes are specific sequences of DNA that encode instructions for the synthesis of proteins. Each gene carries the information necessary for the production of a specific protein or functional RNA molecule. Genes are the basic unit of heredity and play a crucial role in the functioning of cells and organisms.

Therefore, the functional part of DNA includes chromatin, chromosomes, and genes, each playing a unique role in the storage, replication, and expression of genetic information.
