WebTo form highly compacted mitotic and meiotic chromosomes, the radial loops interact with a unique protein structure called the scaffold (see figure 2.8). The scaffold ensures that the … WebThe bacterial chromosome must be compacted approximately 500–1000 times to fit into the nucleoid region within a bacterial cell. To compact the DNA tenfold, the bacterial cell forms microdomainswithin the chromosome (see Figure 2.1). Each microdomain is a loop connected to a centralized core structure composed of DNA binding proteins.
