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. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, … See more Chromatin undergoes various structural changes during a cell cycle. Histone proteins are the basic packers and arrangers of chromatin and can be modified by various post-translational modifications to … See more A variety of internal and external agents can cause DNA damage in cells. Many factors influence how the repair route is selected, including the cell cycle phase and chromatin … See more It has been a puzzle how decondensed interphase chromosomes remain essentially unknotted. The natural expectation is that in the presence of type II DNA topoisomerases that permit passages of double-stranded DNA regions through each other, … See more • Active chromatin sequence • Chromatid • DAnCER database (2010) • Epigenetics See more Chromatin and its interaction with enzymes has been researched, and a conclusion being made is that it is relevant and an important factor in gene expression.
