WebA chromosome is a physical structure that carries all of our genes. They are long, thin structures of protein and DNA, wrapped around a core of histones. Each chromosome is a double-stranded molecule with two long strands of DNA wrapped around a core of histones. The genetic material of an organism is carried within the chromosomes. WebEach chromosome consists of a single very long DNA molecule that has been compacted approximately 10,000-fold by interactions with proteins, such that the resulting chromosome structure fits within a typical eukaryotic nucleus of only 10 microns in diameter. Several levels of structural organisation are involved in the formation of …
