Euchromatin is a lightly packed form of chromatin which is the molecular substance of a chromosome. It is often but not always actively transcribing which means the information in a strand of DNA is copied into a new molecule of RNA.

What do you call the section of dna that is transcribed?
Euchromatin.
What is DNA in a non-dividing cell called?
It's called euchromatin, and is attached to histones.
What does the letter t transcribe to in DNA?
In DNA t is transcribed into t. It is only in RNA that t is transcribed into u.
Is mRNA transcribed from DNA in the nucleus?
yes.
What kinds of genes are transcribed but not translated?
CISTRON
What do you call the section of dna that is transcribed?
Euchromatin.
What is DNA in a non-dividing cell called?
It's called euchromatin, and is attached to histones.
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.
DNA that is spread out in a non dividing cell is called?
Chromatin Chromatin
How are euchromatin and heterochromatin stained?
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 loosely coiled fibers containing protein and DNA within 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!!
When is the repressor protein transcribed?
It is always transcribed.
In eukaryotes what is active transcription generally associated with?
Both euchromatin and histone acetylation.
Why is the DNA in the nucleus loose and not well defined into chromosomes?
In the interphase nucleus the chromatin exists in two forms; loosely coiled form called euchromatin and tightly coiled form called heterochromatin. These two types become much more coiled to form the chromosome at the time of cell division. Now come to the point. When DNA is a bit loosely colied, that is, in the euchromatin, its bases are available for transcription. On the other hand, when it is in the form of heterochromatin, the bases are not accessible for reading by RNA polymerase, hence transcription is not possible. As majority of genes must be transcribed in the nucleus, so the chromosomes must be decondensed to appear in the form of chromatin, and that too in the form of euchromatin. If the DNA remained organized in the form of chromosomes, genes would remain inactive in the sense that they would not be acessible for transcription.
How you do transcribed in a sentence?
Leonardo de Vinci transcribed his thoughts into notebooks.
Where is RNA made during transcription?
In prokaryotes, RNA is transcribed in the cytosol. In eukaryotes, RNA is transcribed in the nucleus.
What does the letter t transcribe to in DNA?
In DNA t is transcribed into t. It is only in RNA that t is transcribed into u.
