The stringy web of genetic material and histone proteins found in the nucleus of eukaryotic cells. During cell division, each strand of DNA coils to form a chromosome.
the DNA complex and associated proteins, most notably histones, that are found in the nucleus of a cell.
The mixture of DNA and protein in a fine network of coiled threads that makes up chromosomes
The complex of DNA and associated histone and non-histone proteins that represents the normal state of genes in the nucleus. It exists in two forms: euchromatin can be transcribed, and heterochromatin is highly condensed and cannot be transcribed.
the generic name for the biochemical molecules that comprise the chromosomes; now knownto be DNA and supporting proteins, primarily histones.
threadlike mass of genetic material consisting principally of DNA; it is present in the nucleus of a nondividing or interphase cell
the complex of DNA and proteins that makes up the eukaryotic chromosome; when a cell is not dividing, chromatin exists as a mass of very long, thin fibers that are not visible under a light microscope
Complex of DNA, histones, and nonhistone proteins from which eukaryotic chromosomes are formed. Condensation of chromatin during mitosis yields the visible metaphase chromosomes. ( Figure 9-29)
the material in the center of the cell (nucleus) that forms chromosomes
Complex of DNA, histones, and nonhistone proteins found in the nucleus of a eucaryotic cell. The material of which chromosomes are made.
The complex of DNA and histone proteins found in chromosomes.
DNA in combination with protein, especially histones. The DNA in the nucleus is packaged as chromatin first, and then as chromosomes. The steps are in the diagram below. The DNA duplex wounds twice around core histone proteins to generate what is called a nucleosome. The strings of nucleosomes coil and form a left-handed superhelix with afiber thicjness of 30 nm. The 30 nm fiber then forms loops around a nuclear matrix. Chromosomes are produced by the stacking of such nuclear matrices.
The network of chromosomes, histones, and other proteins found in the eukaryotic nucleus during interphase. The euchromatin corresponds to regions in which the chromosomes are dispersed, and the heterochromatin to the regions in which chromosomes are cond
The more stainable portion of the cell nucleus contains genetic materials.
compacted DNA and protein.
(Greek, chroma = color) A diffuse material within the nucleus of a non-dividing eukaryotic cell; consists of DNA and proteins.
A histological term referring to the grainy material visible in cell nuclei during interphase; the appearance of the DNA content of the nucleus when the chromosomes are uncoiled.
Substance consisting of DNA plus the protein material around which DNA is wrapped. Chromatin is the material in chromosomes.
Mass of genetic material composed of DNA and proteins that condense to form chromosomes in eukaryotic cell division. Chromatin is located in the cell's nucleus.
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division the chromatin condenses into chromosomes
The nucleoprotein content of the cell nucleus.
Areas or structures within a nucleus of a cell composed of DNA and proteins.
Ribbon-like twists of DNA molecules in the nucleus of the interphase.
(KRO-mah-tihn) The bundled mass of genetic material in the nucleus of a cell, consisting mostly of DNA. It is visible only during interphase.
Material within nucleus made up of DNA and protein.
The substance of chromosomes; now known to include DNA, chromosomal proteins, and chromosomal RNA.
The aggregate mass of dispersed genetic material formed of DNA and protein and observed between period of cell division in eukaryotic cells.
A complex made up of protein and DNA that forms chromosomes.
A complex of DNA and protein in eukaryotic cells that is dispersed throughout the nucleus during interphase and condensed into chromosomes during meiosis and mitosis. PICTURE
The chromosome as it appears in its condensed state, composed of DNA and associated proteins (mainly histones).
a complex of protein and DNA that make up chromosomes.
The material in the nucleus of a cell that makes up chromosomes. Chromatin consists of DNA and proteins.
the complex of nucleic acids and proteins comprising eukaryotic chromosomes
the complex of DNA and protein in the nucleus of the interphase cell. Return to text.
A general term used to refer to the material (DNA) that forms the chromosomes.
Made up of deoxyribonucleohistone (deoxyribonucleic acid connected to a protein structure base), chromatin is the carrier of genes in inheritance. This part of the cell nucleus stains easily.
mass of genetic material that is composed of DNA and proteins. When a cell is "resting" i.e. not dividing, the chromosomes are organized into chromatin.
a material present in chromosomes that is made up of DNA and protein and stains deeply with certain biological stains
The tertiary coiling of the nucleosomes of the chromosomes with associated proteins.
The generic term for any complex of DNA and protein found in the cell's nucleus.
DNA and histone protein which is found in the cell nucleus
Chromatin is the complex of DNA and protein found inside the nuclei of eukaryotic cells. The nucleic acids are in the form of double-stranded DNA (a double helix). The major proteins involved in chromatin are histone proteins, although many other chromosomal proteins have prominent roles too.
