Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures...

Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between proteins and...

Chromatin remodeling is the dynamic modification of chromatin architecture to allow access of condensed genomic DNA to the regulatory transcription machinery...

salt-and-pepper chromatin, also salt-and-pepper nuclei and stippled chromatin, refers to cell nuclei that demonstrate granular chromatin (on light microscopy)...

A Barr body (named after discoverer Murray Barr) or X-chromatin is an inactive X chromosome. In species with XY sex-determination (including humans),...

cancer. Some use the term chromosome in a wider sense, to refer to the individualized portions of chromatin in cells, either visible or not under light...

Bivalent chromatin are segments of DNA, bound to histone proteins, that have both repressing and activating epigenetic regulators in the same region....

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...

a spool. The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set...

Hi-C is a high-throughput genomic and epigenomic technique to capture chromatin conformation. In general, Hi-C is considered as a derivative of a series...

A chromatin variant corresponds to a section of the genome that differs in chromatin states across cell types/states within an individual (intra-individual)...

An active chromatin sequence (ACS) is a region of DNA in a eukaryotic chromosome in which histone modifications such as acetylation lead to exposure of...

as both a barrier to chromatin-mediated silencing via heterochromatin spreading, and blocks interactions between enhancers and promoters. A distinguishing...

prophase. The main occurrences in prophase are the condensation of the chromatin reticulum and the disappearance of the nucleolus. Microscopy can be used...

from chromatin, or reinserted behind the transcribing polymerase. RNA polymerase II is inhibited by α-Amanitin and other amatoxins. α-Amanitin is a highly...

Chromatin assembly factor-1 (CAF-1) is a protein complex — including Chaf1a (p150),  Chaf1b (p60), and p48 subunits in humans, or Cac1, Cac2, and Cac3...

extrudes chromatin to progressively grow a loop. Chromatin on both sides of the cohesin complex is extruded until cohesin encounters a chromatin-bound CTCF...

for Transposase-Accessible Chromatin using sequencing) is a technique used in molecular biology to assess genome-wide chromatin accessibility. In 2013, the...

Chromatin bridge is a mitotic occurrence that forms when telomeres of sister chromatids fuse together and fail to completely segregate into their respective...

hypothesis regarding cellular processes that cause cancer, and for describing chromatin diminution in nematodes. His brother was industrialist Walter Boveri....
