Histones
DNA and histone proteins are packaged into structures called chromosomes. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.  Introduction to Chromosomes. Chromosomes are made up of a strand of DNA tightly wrapped around proteins called histones. This makes the DNA compact and able to fit inside the cell’s nucleus. A gene is a segment of DNA that encodes for a trait. Therefore, genes are located on chromosomes.  Rating Newest Oldest. Best Answer: Effectively, and most importantly, chromosomes are made of DNA. Chromosomes are how your DNA is packaged. It's wrapped around proteins called histones, and then the strong of histones is coiled around and around, and then THAT is coiled even further.  histone / histones. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes. DNA packaging. Each chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins, and contains a portion of the 6,400,000,000 basepairs (DNA building blocks) that make up your DNA. The way DNA is packaged into chromatin is a factor in how protein production is controlled In eukaryotes, DNA molecules are tightly wound around proteins-called histone proteins-which provide structural support and play a role in controlling the activities of the genes. A strand 150 to 200 nucleotides long is wrapped twice around a core of eight histone proteins to form a structure called a nucleosome. DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides. Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes. The nucleosome core particle consists of approximately 147 base pairs of DNA wrapped in 1.67 left-handed superhelical turns around a histone octamer consisting of 2 copies each of the core histones H2A, H2B, H3, and H4. Core particles are connected by stretches of linker DNA, which can be up to about 80 bp long.  The DNA double helix is wrapped in a coil which wraps around proteins. This coil makes another larger one. This coil makes an even larger which makes a coil within the chromosome. Then that one makes the chromosome. Confusing I know, but that's how it is.
