eus = good + chroma = colour; chromatin rich in nucleic acid.
Region of an interphase chromosome that stains diffusely; "normal" chromatin, as opposed to the more condensed heterochromatin.
The part of the genome that is decondensed during interphase, which is transcriptionally active.
The portions of a eukaryotic chromosome that are relatively uncondensed, and are thought to contain active genes.
A chromosome region that stains poorly or not at all; thought to contain the normally functioning genes. Region of eukaryotic chromosome that is diffuse during interphase. Presumably the actively transcribing DNA of the chromosomes. (See heterochromatin)
Chromatin that is diffuse and non-staining during interphase; may be transcribed. (Contrast with heterochromatin.)
The condensed state of chromatin in which it stains lightly, is genetically active, and is partially or fully uncoiled, being the interphase form of the chromosome.
The highly dispersed region of chromatin present during interphase. Euchromatin corresponds to regions of the chomosomes containing actively transcribed genes.
The chromatin that shows the staining behavior characteristic of the majority of the chromosomal complement.
Genetically active regions of the chromosomes.
Regions of chromosomes that stain lightly under analysis and are thought to contain active, functioning genes.
u-KROME-a-tin Light-staining genetic material. 296
Unfolded DNA which is transcriptionally active and stains much more lightly than heterochromatin.
That part of the chromosomal DNA which is genetically active and pale staining with G- and C- banding. Euchromatin is relatively rich in GC base pairs. During interphase it is uncoiled and transcriptionally active whereas heterochromatin is condensed and inactive.
regions of eukaryotic chromosomes that are diffuse during interphase; presumably the actively transcribing DNA of the chromosomes
the less condensed chromatin in the nucleus that is more transcriptionally active than the heterochromatin. Return to text.
The portion of genomic DNA that remains relatively unstained and is transcriptionally active.
The gene-rich areas of a chromosome.
Less condensed portions of chromatin, including most transcribed regions.
Euchromatin is a lightly packed form of chromatin that is rich in gene concentration, and is often (but not always) under active transcription. Unlike heterochromatin, it is found in both eukaryotes and prokaryotes.
