Single strands of DNA are coiled up into structures called chromosomes. DNA has a twisted structure in the shape of a double helix. This means true nucleus so the chromosomes are membrane bound in the nuclear envelope up to early prophase of cell division.

Chromatin structure is also of importance with respect to the DNA replication. Within our chromosomes, sections of DNA are read together to form genes. In addition there is some DNA in each mitochondrion and chloroplast. Joe Hin Tjio of the National Institute of Diabetes and Digestive and Kidney Diseases. Genes were typically thought to reside on chromosomes enclosed in the nucleus of a eukaryotic cell or on the circular DNA genome of a bacterium.
Eukaryotic cells store their genetic material DNA in chromosomes in the nucleus. Changes in chromatin structure are effected mainly by methylation and acylation of the nucleosome proteins.
