(Phys.org)—The base-pairing properties of DNA, combined with our abilities to create synthetic DNA in the laboratory have led to advances in nanoscale architecture and molecular device designs. Less research has been done ...
Scientists have determined the first 3D structures of intact mammalian genomes from individual cells, showing how the DNA from all the chromosomes intricately folds to fit together inside the cell nuclei.
