DNA Packaging - an overview ScienceDirect Topics

WitrynaIn order to fit the DNA molecules into the nucleus, it needs to be packed into an extremely compressed and compact structure called chromatin. During the initial stages of DNA packaging, the DNA is reduced to an 11 nm fibre that denotes approximately 5-6 folds of compaction. This is achieved through a nucleosome order of packaging. WitrynaEuchromatin is a form of chromatin that is lightly packed as opposed to heterochromatin, which is densely packed. The presence of euchromatin usually reflects that cells are transcriptionally active, i.e. they are actively transcribing DNA to mRNA. Hence, the correct answer is (B) Was this answer helpful? 0. 0.

You don’t need to live every day with a capsule wardrobe to pack one when you travel. A capsule wardrobe is simply clothing that can all be mixed and matched and worn together. Euchromatin (also called "open chromatin") 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 stands in contrast to heterochromatin, which is tightly packed and less accessible for transcription. 92% of the … Zobacz więcej Euchromatin is composed of repeating subunits known as nucleosomes, reminiscent of an unfolded set of beads on a string, that are approximately 11 nm in diameter. At the core of these nucleosomes … Zobacz więcej Euchromatin resembles a set of beads on a string at large magnifications. From farther away, it can resemble a ball of tangled thread, … Zobacz więcej Euchromatin is primarily regulated by post-translational modifications to its nucleosomes’ histones, conducted by many histone-modifying enzymes. These modifications occur on the histones’ N-terminal tails that protrude from the nucleosome … Zobacz więcej Transcription Euchromatin participates in the active transcription of DNA to mRNA products.
