The Molecular Model of DNA and its Replication

SCIENTIFIC CONCEPTS / PROCESSES

• Build a segment of the DNA molecule and see what a double helix is like
  
• Model can be unzipped allowing for replication of DNA segment

• Double nitrogen pyrimidine bases are constructed proportionately larger in diameter than the single nitrogen purine bases
  
• Bases are linked by a unique hydrogen bond
  
• The deoxyribose sugar is pentagon-shaped, representing its actual molecular structure

Includes 30 student worksheets, 1 instruction manual, and 12 packets of color-coded components.
