difference between heterochromation and euchromation?
Answers
Answer:
- Heterochromatin is defined as the area of the chromosome which is darkly stained with a DNA specific stain and is in comparatively condensed form. Euchromatin is defined as the area of the chromosome which is rich in gene concentration and actively participates in the transcription process.
Answer:
Parameter Heterochromatin Euchromatin
Meaning It is a form of DNA in the chromosome that has the characterization of tight packing It is a form of DNA in the chromosome that has the characterization of loose packing
Type of stain Dark stain Light stain
Density of DNA High density of DNA Low density of DNA
Transcriptional activity Little or no transcriptional activity here There is the active participation of the transcriptional process here
Their presence They exist at the periphery of the nucleus. Furthermore, they exist only in eukaryotic cells They exist in the nucleus’s inner body. Furthermore, they exist in eukaryotic as well as prokaryotic cells
Molecular organization of euchromatin and heterochromatin Coiling is compact, regions are sticky, there is no change in the phenotype of an organism, gene expression regulation is possible, and maintenance of the cell’s structural integrity Coiling is loose, regions are non-sticky, variation may occur due to the effect in DNA at the time of the genetic process, genetic variations are possible, and genetic transcription takes place
