Cell to Helix How is all that DNA arranged to fit into a single cell!? Over 3 billion base pairs coiled, wrapped, and jumbled into what eventually looks like a tangled mess within the nucleus. Yet it's somehow still accessible for replication, transcription, and repair--- blows my mind! Trace the purines and pyrimidines from the nucleus to chromosome, super-coil, scaffolding, histones, and finally to the double helix :) FINE ART PRINT • Museum quality fine art paper • Acid-free, 100% cotton rag, lightly textured • Archival pigment inks • Signed by artist • Unframed Use this listing for the Buy 3 Get 1 Free: https://www.etsy.com/listing/229635451/sale All artwork is original, created and owned by Sandra Black. ©Sandra Black http://www.SandraBlackArt.com
