Chromosomes are highly organized structures that hold genetic information in the form of DNA. These structures reside within the nucleus of a cell. The DNA is tightly packed to make up the chromosomes, utilizing molecules known as histones to assist in this packing. The 46 chromosomes of a human cell are organized into 23 pairs, and the two members of each pair are said to be homologues of one another (with the slight exception of the X and Y chromosomes; see below). Human sperm and eggs, which have only one homologous chromosome from each pair, are said to be haploid ( 1n ).The short answer is that chromosomes found in the nucleus of plant cells are composed of chromatin (optional reading). Chromatin is made up of DNA wrapped around proteins, called histones. These proteins around which the DNA wraps are called histones. We’ll start with the structure of DNA and build up to a chromosome.Mitosis describes the division of one cell into two identical daughter cells. It occurs in several stages, each of which consists of a stereotyped set of changes in cell contents and structure. In this article, we will look at the stages of mitosis and its clinical relevance.

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.During the majority of the cell’s life, chromosomes are composed of only one copy and they are not tightly compacted into chromosomes. When fully compact, the pairs of identically packed chromosomes are bound to each other by cohesin proteins. The connection between the sister chromatids is closest in a region called the centromere.In Summary: Chromosome Structure. DNA in eukaryotes is highly structured and organized in all stages of an organism’s life. Diploid organisms contain a pair of each chromosome; humans have 23 pairs for a total number of 46 chromosomes. Pairs of chromosomes, also known as homologous chromosomes, contain the same genes …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. Genes are part of cell structures called chromosomes. In multicellular organisms, chromosomes are found in the nucleus of the cell. Each of these chromosomes contains one, long molecule of DNA, or d eoxyribo n ucleic a cid. A gene is a specific stretch of this DNA molecule. Each chromosome in the cell contains many genes. Chromosome I contains most of the essential genes, while chromosome II only carries a few essential functions and is probably derived from a megaplasmid [Heidelberg et al., 2000]. The replication origins of these two chromosomes localize to distinct positions during all stages of the cell cycle [Fogel and Waldor, 2005]. The origin …Chromatin in turn forms larger loops and coils to form chromosomes. DNA is tightly packed in the nucleus of every cell. DNA wraps around special proteins called histones, which form loops of DNA called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.DNA is normally tightly packed into the nucleus of a eukaryotic cell, through protein-DNA complexes that form the characteristic condensed ‘chromosome’ shape. DNA compacts even further in preparation for cell division.Both prokaryotic and eukaryotic cells allow for designated areas for housing DNA. Genes for prokaryotic cells are located on multiple linear DNA molecules while genes for eukaryotic cells are located on a single linear chromosome.
