What is the difference between chromatin and euchromatin?

Heterochromatin and euchromatin are two major categories of chromatin higher order structure. Heterochromatin has condensed chromatin structure and is inactive for transcription, while euchromatin has loose chromatin structure and active for transcription.

What is difference between chromatin and chromatin?

The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.

Difference between Chromosomes and Chromatin
Composed of nucleosomes They are condensed chromatin fibers
Unpaired Paired

What is euchromatin and its function?

Euchromatin is the part of the chromatin involved in the active transcription of DNA into mRNA. As euchromatin is more open in order to allow the recruitment of RNA polymerase complexes and gene regulatory proteins, so transcription can be initiated.

What do u mean by euchromatin?

Euchromatin is the genetically active region of the chromosome. It contains structural genes that are replicated during G1 and S phase of interphase by allowing polymerases to access the genes.

Does chromatin have RNA?

Whether RNA itself plays a direct structural role in chromatin is, however, not known. Here, we report results indicating that RNA plays a general structural role in eukaryotic chromatin. Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).

What are the 2 types of chromatin?

Chromatin exists in two forms. One form, called euchromatin, is less condensed and can be transcribed. The second form, called heterochromatin, is highly condensed and is typically not transcribed. Under the microscope in its extended form, chromatin looks like beads on a string.

What is true euchromatin?

Euchromatin is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.

Is chromatin a prokaryote?

Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones. The structure of chromatin is scaffolded, with three distinct levels.

How many types of chromatin are there?

Chromatin exists in two forms: heterochromatin (condensed) and euchromatin (extended).

What is meant by transcription?

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
