DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Novel Tool Uses DNA Barcode System for Deep-Tissue RNA and Protein Imaging

For the Liu Lab, necessity is truly the mother of invention. The researchers were examining how the 3D organization of the genome controls development and needed to image hundreds of RNA molecules in a thick tissue sample to understand where and how genes were being expressed in cells.
