If the DNA from all 46 chromosomes in a human cell nucleus was laid out end to end, it would measure approximately two meters. However, the diameter would be only 2 nm. Considering that the size of a typical human cell is about 10 µm (100,000 cells lined up to equal one meter), …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.H2A, H2B, H3 and H4 are the core histones. Two H3 and H4 dimers and two H2A and H2B dimers form an octamer. Linker histones lock the DNA in place onto the nucleosome and can be removed for transcription. Histones can be modified to change the amount of packaging a DNA does. The addition of the methyl group increases the hydrophobicity of …chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes.

We can compare this to the more diffuse chromatin, which refers to the less condensed, more dispersed form of DNA found during the interphase of the cell cycle. The former, on the other hand, is often seen during active cell division only.

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 ).Wiki User. ∙ 13y ago.

DNA is normally tightly packed into the nucleus of a eukaryotic cell, through protein-DNA complexes that form the characteristic condensed ‘chromosome’ shape.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.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.
