Researchers explain the organization of DNA in chromosomes from repetitive interactions between nucleosomes
An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study published in the journal Small Structures demonstrates that the multilaminar organization of DNA, proposed from previous experimental research carried out at the UAB, is fully compatible with the structural and functional properties of chromosomes. This organization can be explained by weak interactions between nucleosomes, which are the repetitive blocks that fold the DNA double helix.
