WHAT IS Heterochromatin and euchromatin?

Euchromatin is loosely coiled DNA that is transcriptionally active. Heterochromatin is tightily packed DNA that is transcriptionally inactive.


Heterochromatin and euchromatin?

Euchromatin is loosely coiled DNA that is transcriptionally active. An increased amount of euchromatin indicates an active cell. Heterochromatin is tightly packed DNA that is transcriptionally innactive.


What are the two types of chromatin and what are the differences?

the two types of chromatins are euchromatin and heterochromatin.They are different in that heterochromatin is coiled while euchromatin is not coiled.It is this coiling that makes heterochromatin inactive and therefore less in the nucleus when the nucleus is actively involved in protein synthesis.On the other hand,euchromatin is active because its DNA is exposed. When viewed under a microscope,the two chromatins have different stains.


Some portions of chromosomes are condensed and DNA is not expressed these dark-stained areas are called?

Heterochromatin is dark stained area caused by condensed chromosomes or DNA. Heterochromatin is located near between the inner membrane and the nucleoplasm.


How does chromatin structure affect gene expression?

When chromatin is tightly compacted and dense, it's called Heterochromatin. When chromatin is loosely packed, its called Euchromatin. Euchromatin is easily accessible to transcription enzymes, while herterochromatin makes transcription impossible because the enzymes cannot access the DNA. Therefore, a gene within heterochromatin cannot be expressed. Also, look up how histone modifications such as histone acetylation affect gene expression.

Is heterochromatin transcribed?

No. Heterochromatin is unexpressed, so it will not transcribed by RNA. Euchromatin is transcribed.


Heterochromatin differs from euchromatin in that heterochromatin?

Heterochromatin is more densely packaged than euchromatin and is much less transcriptionally active. Examples of heterochromatic DNA would be the centromeric and telomeric regions of a chromosome.


The nucleus of an atom is made of?

Chromatin, divided into heterochromatin and euchromatin.


Difference between euchromatin and heterochromatin?

-> Euchromatin is a lightly packed form of chromatin (DNA, RNA and protein) that is rich in gene concentration.Heterochromatin is a tightly packed form of DNA.->Euchromatin is found in both cells with nuclei (eukaryotes) and cells without nuclei (prokaryotes) while heterochromatin is found only in eukaryotes.

What is the difference between euchromatin an hetrochromatin?

Hetrochromatin is non-expressed material that being stained significantly in G-banding, predominantly repeated sequences. Where as Euchromatin is expressed material that is lightly stained.


Is chromatin loosely coiled fiber that contains fiber and protein within the nucleus?

Chromatin is the generic term for DNA (not "fiber") wound around proteins called histones. From the description you've given, it sounds like you're talking about euchromatin.There are generally two types of chromatin: euchromatinand heterochromatin. Under the microscope, heterochromatin tends to stay at the periphery of the nucleus, while euchromatin tends to stay central in the nucleus. Also microscopically, euchromatin is a bit lighter (ie, it doesn't stain as heavily) than heterochromatin, reflecting the fact that euchromatin is less dense than heterochromatin. The decreased density has to do with euchromatin being loosely wound around histones, whereas heterochromatin is wound rather tightly. Heterochromatin also has a number of other chromatin-modifying proteins around that prevent it from coming undone easily.The functional difference between the two types of chromatin has to do with how effectively DNA transcription (the process by which DNA is transcribed to RNA) can occur. The dense heterochromatin is so tightly wound and so tightly packed with associated proteins that the DNA transcription machinery can't get access to the DNA contained within the heterochromatin. Only the loosely wound euchromatin will permit the machinery to gain access to its DNA. Therefore, generally euchromatin contains DNA that is being actively transcribed, while heterochromatin is transcriptionally silent.THE ANSWER IS CHROMATIN!!

What is the the relationship of chrosomes to chromatin?

Chromatin is the stuff they´re made out of. Densely condensed chromatin is known as heterochromatin and not fit to transcribe, loosely packed euchromatin can be transcribed easily.
