euchromatin การใช้

• Euchromatin participates in the active transcription of DNA to mRNA products.
• Relaxed, transcriptionally active DNA is referred to as euchromatin.
• TERRA can also regulate telomere length by increasing euchromatin formation.
• Evolutionary dynamics of segmental duplications from human Y-chromosomal euchromatin / heterochromatin transition regions.
• Active transcription units are clustered in the nucleus, in discrete sites called transcription factories or euchromatin.
• Euchromatin modifications are also common which is also consistent with the state of euchromatin found in ESCs.
• Euchromatin modifications are also common which is also consistent with the state of euchromatin found in ESCs.
• The X chromosome is notably larger and has a more active euchromatin region than its Y chromosome counterpart.
• However, on a larger scale, chromosomes are heterogeneous in the context of euchromatin and heterochromatin composition.
• There are also three additional euchromatin / heterochromatin transition regions for a total of four on the Y chromosome.
• On the other hand, interstitial region segmental duplications are distributed on the euchromatin between the pericentromeric and subtelomeric regions.
• The other 22Mb euchromatin region also has a unique genetic structure with large gene-rich palindromes . [ 4]
• The structure of euchromatin is reminiscent of an unfolded set of beads along a string, wherein those beads represent nucleosomes.
• The latter, known as euchromatin, is transcriptionally active, whereas the former, known as heterochromatin, is transcriptionally inactive.
• DNA packaged in heterochromatin, such as the Xi, is more condensed than DNA packaged in euchromatin, such as the Xa.
• Tsix prevents the accumulation of Xist on the future active female X chromosome to maintain the active euchromatin state of the chosen chromosome.
• In particular, it is believed that the presence of methylated lysine 4 on the histone tails acts as a general marker for euchromatin.
• The pericentromeric region on the Y chromosome is a 450kb euchromatin island between the satellite three sequence and the long arm of the chromosome.
• There is therefore a direct link to how actively productive a cell is and the amount of euchromatin that can be found in its nucleus.
• In contrast to conventional rods, inverted rods have heterochromatin in the center of their nuclei and euchromatin and other transcription factors along the border.
