Webchromosomes – short, rod like bodies – while at interphase, the chromosomes are decondensed within the interphase nucleus (Figure 2). The study of the chromosome and its organization involves cytogenetics, and the field of molec-ular cytogenetics has developed to understand DNA sequence and the molecular structure of the … WebJun 1, 2024 · Two 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.
