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...

Chromatins appear as bead-like structures on the linker DNA, known as a nucleosome.Nucleosomesfurther condense and coil to shorten the chromosome by almost 50 times. Finally, it is additionally packed with the help of fibrous protein. However, the extent of DNA coiling and condensation differs ...

The relationships between chromosomal compartmentalization, chromatin state and function are poorly understood. Here by profiling long-range contact frequencies in HCT116 colon cancer cells, we distinguish three silent chromatin states, comprising two ty

If the cell would go through cell division (such as mitosis/meiosis), the cell prepares by chromatins condensing into thicker structures (now referred to as chromosomes) and duplicating the DNA molecule within each chromatin (via DNA replication). Thus, each chromosome would be comprised of two...
