Chromosomes... Chromosomes 8-1 Chromosome structure During cellular phone division, desoxyribonucleic venereal disease is coiled into very dense structures in the nucleus called Chromosomes. Chromosomes are rod-shaped structures made of desoxyribonucleic acid and proteins. Each chromosome is a molecule of DNA. In eukaryotic cells, the chromosomes timber up as darkened structures. The DNA is associated with hist unitary or non-histone proteins. DNA wraps rough histone proteins to maintain its shape. Non-histone proteins are used to witness the activity of particularised regions of DNA. Each side of a chromosome is called a chromatid. Each one of the two chromatids has the same DNA as from all(prenominal) oneother.
The chromatids are attached in the center called the centromere. When the cell divides into two separate cells, each side receives a chromatid from each chromosome. Between cell division, the DNA is coiled less tightly so the DNA tolerate be easily enounce and direct the cells activity. The less tightly coiled DNA-protein complex is called chromatin.
