Biology definition: Chromatin is a substance made up of DNA or RNA and proteins, such as histones. It condenses during cell division (mitosis or meiosis) and becomes a chromosome. Chromatins are“unwound” condensed structures whereas chromosomes are highly packaged and more condensed than chroma...
Kyle has taught college level biology and helped with middle-school science programs. Have you ever wondered how or why the cells of our body store information? Many of us know that the molecule DNA contains all the information that makes us who we are. After this lesson you will be able...

Haicovan Attikum,Susan M.Gasser, inTrends in Cell Biology, 2009 Chromatin remodelingrefers to a variety of changes in nucleosomal organization, all of which start with changes in DNA–histone contacts. Chromatin-remodeling complexes use the energy from ATPhydrolysisto induce these changes, leading ...
The biology of real chromosomes in the cell nucleus is undoubtedly highly complex, with a myriad of details affecting biological outcomes. However, the overall behavior of chromosomes in 3D in the cell nucleus is still expected to be consistent with a relatively simple physical system: that of po...
The classic definition of heterochromatin originated from staining mitotic chromosomes74 and later came to be associated with histone modifications75. We now have a more nuanced understanding of the molecular details, including several types of repressive histone modifications and associated proteins and the...

Due to the integration of HPV at varying genomic regions, these analyses compared one sample to a population and therefore suffer from a lack of statistical power. We compensated for such limitations by using a restrictive definition for considering outlier genes and visualizing raw signal and ...
