(biology) A complex of DNA, RNA and proteins within the cell nucleus out of which chromosomes condense during cell division.
(genetics) After DNA replication either of the two connected double-helix strands of a metaphase chromosome that separate during mitosis
Tissue which is capable of being stained by dyes.
one of two identical strands into which a chromosome splits during mitosis.
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.
one of two identical strands into which a chromosome splits during mitosis
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division the chromatin condenses into chromosomes
A chromatid (Greek khrōmat- 'color' + -id) is one half of a duplicated chromosome. Before replication, one chromosome is composed of one DNA molecule.
Chromatin is a complex of DNA, protein and RNA found in eukaryotic cells. Its primary function is packaging long DNA molecules into more compact, denser structures.
