WebFigure 12.2. 4: Double-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of “beads on a string.”. The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the duplicated chromosomes condense even further. DNA replicates in the S phase of interphase. WebTwo major mechanisms of chromosome organization. Nucleosomal arrays create a chromatin fiber that is folded differently in interphase and metaphase. In mitosis, loop extrusion by condensins leads to the formation of a dense array of loops: condensins form a scaffold with loop emanating from it. ...
