Definitions and meanings of "Chromatin"

What do we mean by chromatin?

A complex of nucleic acids and proteins, primarily histones, in the cell nucleus that stains readily with basic dyes and condenses to form chromosomes during cell division. noun

In bot, a name proposed for that portion of the substance of the nucleus which is readily colored by staining agents. noun

In zoology, that portion of the substance of an ovum which has a special affinity for coloring matter and readily becomes colored; chromophilous protoplasm, which in the process of maturation of the ovum forms various colored figures, as disks and threads: the opposite of achromatin. noun

In cytology, that portion of the cell-nucleus in animals and plants which takes on a deep color in certain stains (carmine, hematoxylin, etc.): opposed to achromatin. noun

Tissue which is capable of being stained by dyes. noun

The deeply staining substance of the nucleus and chromosomes of eukaryotic cells, composed of DNA and basic proteins (such as histones), the DNA of which comprises the predominant physical basis of inheritance. It was, at the beginning of the 20th century, supposed to be the same substance as was then termed idioplasm or germ plasm. In most eukaryotic cells, there is also DNA in certain plasmids, such as mitochondria, or (in plant cells) chloroplasts; but with the exception of these cytoplasmic genetic factors, the nuclear DNA of the chromatin is believed to contain all the genetic information required to code for the development of an adult organism. In the interphase nucleus the chromosomes are dispersed, but during cell division or meiosis they are condensed into the individually recognizable chromosomes. The set of chromosomes, or a photographic representation of the full set of chromosomes of a cell (often ordered for presentation) is called a karyotype. noun

A complex of DNA, RNA and proteins within the cell nucleus out of which chromosomes condense during cell division. noun

The readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it condenses into chromosomes noun

A complex of DNA, RNA and proteins within the cell nucleus out of which chromosomes condense during cell division.

This and the stoichiometry of the tetramer implied a unit of structure in chromatin based on two each of the four histones, or an (H2A) 2 (H2B) 2 (H3) 2 (H4) 2 octamer. ❋ Unknown (2007)

There is evidence of complex quantum electrodynamic operations in chromatin – the form of DNA operative when the cell isn't replicating (thus dividing its DNA into chromosomes). ❋ Unknown (2007)

Rather, the DNA in chromatin must be wrapped on the outside of the histone octamer. ❋ Unknown (2007)

It is, however, evident that this action on chromatin is most important for proper functioning of the genome and for maintenance of genome integrity. ❋ Unknown (2006)

I was studying the structure of genes in chromatin and had the good fortune of participating in a revolution made possible by recombinant DNA technology. ❋ Unknown (2005)

There's a "biology teacher" who doesn't know what chromatin is (and never heard of a histone code), a "physics teacher" who never got past Newtonian mechanics, a "theologian" who has no idea how Jews and orthodox Christians view Genesis I and II, etc., etc. ❋ Unknown (2005)

There's a "biology teacher" who doesn't know what chromatin is (and never heard of a histone code), ❋ Unknown (2005)

The DNA-protein complex of cell nuclei, chromatin, is condensed to chromosomes during cell division. ❋ Unknown (1982)

In non-dividing cells, DNA is associated with proteins to form the so-called chromatin, with more condensed “heterochromatin” at the periphery and less condensed “euchromatin” in the interior. ❋ Unknown (2009)

In the nucleus is a material termed chromatin which bears the factors of heredity. ❋ William Thomas Councilman (N/A)

Each original cell contains a substance which, on account of its being easily colorable with artificial stains, is called chromatin, and this chromatin is believed to be the bearer of the hereditary qualities. ❋ Arthur Herbert Gray (1912)

To be sure there is a remarkable substance, called chromatin because of its capacity for taking up certain dyes, which evidently plays some profoundly important part in the processes of development. ❋ Bertram Coghill Alan Windle (1893)

Indeed the karyokinetic process may begin in both the pronuclei before their junction is effected; and, even when their junction is effected, it does not appear that complete fusion of the so-called chromatin elements of the two pronuclei takes place. ❋ George John Romanes (1871)

The protein encoded by ARID1A is a component of a cellular structure called a chromatin remodeling complex. ❋ Unknown (2010)

It is involved in a process called chromatin remodeling, which helps squeeze DNA into cells and control when and how it gets "read" to perform a biological function. ❋ Unknown (2010)

"Our calculations should certainly help to decode the so-called chromatin code, the basis for which is not well understood", says Gerland. ❋ Unknown (2010)

In non-dividing cells, DNA is associated with proteins to form the so-called chromatin, with more condensed "heterochromatin" at the periphery and less condensed "euchromatin" in the interior.
