The genome (the code of life) is organized in the form of folded chromosomes within the nucleus of cells. This three-dimensional organization of the genome is fundamental, as it determines which genes are switched on and off in each cell type. Comparing whole genome sequences from different species allows for the study of evolutionary dynamics and the role of chromatin organization in the speciation process.
