that A bound to T and C bound to G within the molecular structure of DNA (Figure 2). Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work ...
is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like structures called chromosomes.
