A single molecule of deoxyribonucleic acid and a protein make up each chromosome (DNA). As bundles of DNA that are tightly wound, chromosomes are found inside the nucleus of practically all of the cells in our body. Histone-like proteins, which give chromosomes their distinctive shape, keep DNA securely wound around them.

Definition. A histone is a protein that provides structural support for a chromosome. Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. To do that, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact shape. Histones also play a role in the regulation of gene expression.Chromatin and Chromosomes. Packed inside the nucleus of every human cell is nearly 6 feet of DNA, which is subdivided into 46 individual molecules, one for each chromosome and each about 1.5 inches long. Collecting all this material into a microscopic cell nucleus is an extraordinary feat of packaging. For DNA to function when necessary, …breakdown of complex molecules and the subsequent release of energy. and more. ...

The center of a chromosome that holds two chromatids together, also where spindle fibers are attached during division. What is a chromatid? Half of an x-shaped chromosome. One chromatid is replicated to make an x-shaped chromosome. What is a chromosome? (two answers) One chromatid, combined with a centromere (called a single-stranded …The structural unit of chromatin is the nucleosome. Each nucleosome consists of eight units of nuclear proteins called histones (two each of histones H2A, H2B, H3, and H4) associated with 146 nucleotide pairs of DNA and a stretch of linker DNA of varying length. The diameter of the nucleosome “bead,” or core particle, is about 10 nm. Chromosomes are structures of DNA and proteins that package the genetic material of cells. They are made of nucleosomes, which are composed of DNA and histones. Chromosomes are more tightly packed in eukaryotic cells than prokaryotic cells, and they have different levels of condensation and accessibility. Wiki User. ∙ 13y ago.

Chromatin consists of DNA that is tightly coiled around ...DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.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. Explanation:Chromosomes and Chromatin. Not only are the genomes of most eukaryotes much more complex than those of prokaryotes, but the DNA of eukaryotic cells is also organized differently from that of prokaryotic cells. The genomes of prokaryotes are contained in single chromosomes, which are usually circular DNA molecules.

Description. This animation shows how DNA molecules are packed up into chromosomes. DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.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. Explanation:Chromosomes are structures within cells that contain genetic material. Genetic material is composed of DNA, which stands for deoxyribonucleic acid. DNA molecules are tightly packed together with proteins to form chromosomes.A chromosome is a package of DNA with part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome -forming packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA ...Each chromosome includes a single, linear molecule of DNA with its own set of genes. Chromosomes are numbered according to their size, and genes are arranged along them in a specific order. So a gene near the tip of the short arm of chromosome 4 in one person will be found in the same location in everyone. This means that each of our genes can ...Pairs of chromosomes, also known as homologous chromosomes, contain the same genes though there may be differences between the version of gene on each member of the pair. DNA is normally tightly packed into the nucleus of a eukaryotic cell, through protein-DNA complexes that form the characteristic condensed ‘chromosome’ shape.Having discussed the DNA and protein molecules from which the 30-nm chromatin fiber is made, we now turn to the organization of the chromosome on a more global scale. As a 30-nm fiber, the typical human chromosome would still be 0.1 cm in length and able to span the nucleus more than 100 times. Clearly, there must be a still higher level of folding, …
