WebQuestion: DNA is a macromolecule that stores information. Which component of DNA is the source of this information? A) the sugar B) the phosphate group C) the base D) the histone E) the ladder 30) A person's unique DNA is carried within some of the cells and tissues of their body. These include all of the following except A) intestines B) blood. The histone code is a hypothesis that the transcription of genetic information encoded in DNA is in part regulated by chemical modifications (known as histone marks) to histone proteins, primarily on their unstructured ends. Together with similar modifications such as DNA methylation it is part of the epigenetic code. Histones associate with DNA to form nucleosomes, which themselves bundle to form chromatin fibers, which in turn make up the more familiar chromosome. Histones … glock careers smyrna ga
