chromatin definition

  • noun:
    • A complex of nucleic acids and proteins, mainly histones, when you look at the cellular nucleus that spots easily with standard dyes and condenses to make chromosomes during cell unit.
    • A complex of DNA, RNA and proteins inside the cellular nucleus away from which chromosomes condense during mobile unit.
    • structure which can be effective at being stained by dyes.
    • The deeply staining material of nucleus and chromosomes of eukaryotic cells, made up of DNA and standard proteins (such as for example histones), the DNA of which includes the predominant physical basis of inheritance. It absolutely was, at the beginning of the 20th century, said to be equivalent substance as was then termed idioplasm or germ plasm. Generally in most eukaryotic cells, additionally there is DNA in a few plasmids, such as for example mitochondria, or (in-plant cells) chloroplasts; however with the exclusion of those cytoplasmic hereditary factors, the nuclear DNA associated with chromatin is known to consist of all of the hereditary information required to code for development of an adult system. Inside interphase nucleus the chromosomes are dispersed, but during cellular division or meiosis these are generally condensed in to the independently identifiable chromosomes. The set of chromosomes, or a photographic representation regarding the full set of chromosomes of a cell (frequently ordered for presentation) is called a karyotype.
    • In bot, a name proposed for that portion of the substance regarding the nucleus which can be easily colored by staining agents.
    • In zoology, that portion of the material of an ovum that has a special affinity for coloring matter and readily becomes coloured; chromophilous protoplasm, that the process of maturation of ovum forms various-colored numbers, as disks and threads: the opposite of achromatin.
    • In cytology, that percentage of the cell-nucleus in animals and flowers which assumes a-deep color in some stains (carmine, hematoxylin, etc.): opposed to achromatin.
    • the readily stainable compound of a cell nucleus composed of DNA and RNA and various proteins; during mitotic unit it condenses into chromosomes
    • A complex of nucleic acids and proteins, mostly histones, when you look at the cellular nucleus that spots readily with fundamental dyes and condenses to create chromosomes during mobile division.
    • A complex of DNA, RNA and proteins in the cellular nucleus regarding which chromosomes condense during mobile division.
    • Tissue which can be capable of being stained by dyes.
    • The profoundly staining compound of nucleus and chromosomes of eukaryotic cells, made up of DNA and fundamental proteins (including histones), the DNA of which includes the prevalent physical foundation of inheritance. It had been, at the beginning of the 20th century, said to be similar material as ended up being called idioplasm or germ plasm. In most eukaryotic cells, addititionally there is DNA in certain plasmids, including mitochondria, or (in plant cells) chloroplasts; but with the exclusion of those cytoplasmic genetic facets, the atomic DNA of chromatin is known to consist of all hereditary information expected to code for development of a grownup organism. In interphase nucleus the chromosomes are dispersed, but during cellular unit or meiosis these are generally condensed into the separately familiar chromosomes. The set of chromosomes, or a photographic representation associated with full group of chromosomes of a cell (usually ordered for presentation) is known as a karyotype.
    • In bot, a name suggested for that percentage of the substance regarding the nucleus that will be readily colored by staining representatives.
    • In zoology, that portion of the compound of an ovum that has an unique affinity for coloring matter and easily becomes colored; chromophilous protoplasm, which in the entire process of maturation for the ovum types various-colored figures, as disks and threads: the exact opposite of achromatin.
    • In cytology, that percentage of the cell-nucleus in animals and plants which assumes a-deep shade in a few spots (carmine, hematoxylin, etc.): against achromatin.
    • the readily stainable compound of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic unit it condenses into chromosomes
