The volume of the nucleus occupied by histone octamers. Introduction: Cell is the basic unit of life. It contains a nucleus that has the genetic material as DNA. The monomers that make up the DNA are nucleotides . There are four different nucleotides. These are adenine (A), thymine (T), cytosine (C), and guanine (G). The nucleotides are covalently joined together in a sequence through the sugars and phosphates. This forms a backbone of alternating sugar-phosphate–sugar-phosphate. The histone protein helps in chromosome packing into the nucleosome. An individual nucleosome core particle consists of a complex of eight histone proteins called histone octamers in which DNA is wrapped.

*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
