Deoxyribonucleic acid (dna) is a polymer of nucleotides that provides the chemical basis for inheritable characteristics of all cellular organisms. This activity is a group-work tutorial where students examine the structure of dna using molymod molecular models™ and build their own dna sequence model.

Structure of dna

Each dna molecule in the cell nucleus consists of two strands of sugars and phosphates with pairs of nitrogen bases forming cross links this structure is twisted. Manuscript predating watson and crick article becomes an official part of the scientific record. This is much like what a strand of dna looks like the structure is called a double helix dna is essentially made of sugar, phosphate and bases, bonded.

Dna or deoxyribonucleic acid is a long molecule that contains our unique genetic illustration showing the double helix structure of dna. The observation that dna was double-stranded was of crucial significance and provided one of the major clues that led to the watson-crick structure of dna.
