How Does Chromosome Compaction Work at Molly Paton blog

How Does Chromosome Compaction Work. Compaction of human embryos results from reducing a compaction parameter α = cos (θ e /2) = γ cc /2γ cm, where θ e is the external contact angle between cells (supplementary note and fig. In the first level of compaction, short stretches of the dna double helix wrap around a core of eight histone proteins. The answer to this question lies in the fact that certain proteins compact. Two new studies report observations of dna compaction by eukaryotic and bacterial condensin molecules in real time using magnetic and optical trapping micromanipulation techniques. Amazingly, although the dna is very tightly folded, it is compacted in a way that allows it to easily become available to the many enzymes in the cell that replicate it, repair it, and use. In organisms ranging from bacteria to human, the much longer dna is highly compacted to fit inside the nucleoid or cell. Mitotic chromosomes must be organised into a highly ordered and compacted form to allow proper segregation of dna during each round of cell division. Here we test the hypothesis that chromosomes are compacted by enzymatic machines that actively extrude chromatin loops. There are a number of ways that chromosomes are compacted.
