How is all that DNA arranged to fit into a single cell!? Over 3 billion base pairs coiled, wrapped, and jumbled into what eventually appears to be a tangled mess within the nucleus. Yet it is somehow still accessible for replication, transcription, and repair. It is mind blowing! Trace the purines and pyrimidines from the nucleus to chromosome, super-coil, scaffolding, histones, and finally to the double helix :)Ships flat against backing board and within a clear art sleeve.
