WebTranscription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.

Chromatin remodeling - Wikipedia

WebChromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell. This chromatin is located within the cell nucleus. The main functions of this genetic material include: Preventing DNA damage. Tightly packing the DNA to fit into the cell. WebPlasticity is an essential condition for cancer cells to invade surrounding tissues. The nucleus is the most rigid cellular organelle and it undergoes substantial deformations to get through environmental constrictions. Nuclear stiffness mostly depends on the nuclear lamina and chromatin, which in turn might be affected by nuclear architectural proteins. Among … record of ragnarok s1 ep 6 english dub

Our DNA is packaged tightly into chromosomes and squeezed into a tiny nucleus. To achieve this, DNA is wrapped around unique proteins called histones, and the resulting DNA-protein complex is called chromatin. Histones are enzymatically modified with acetyl, methyl, or phosphate groups, for example. WebNucleosomes are made up of eight histones, which are a group of related proteins found in eukaryotes. Nucleosomes are an important component of the chromatin (the material that chromosomes are made of). Nucleosomes help to organize, compact, and regulate the DNA. This is also discussed in this video starting around. record of ragnarok qin
