30-2" PVC, white bonds (H bonds)
Lab procedure and Answer key PDF on this website.

This kit gives students a chance to "handle" a molecule of DNA by first constructing 24 nucleotides from sugars, bases, and phosphates. The nucleotides are then assembled into a DNA duplex containing 12 base pairs. Different colored tubes, used for bonds, highlight the difference between ordinary covalent and hydrogen bonding. The kit can be used to show a variety of base sequences and the point mutation that causes sickle cell anemia.

Use of the kit can also be integrated with a study of the dictionary of the genetic code, transcription, and translation.

When used together, three or four sets can illustrate DNA's helical form or replication of the molecule.

Lab procedure
Answer key

There are enough carbon atoms in this kit to make a triglyceride that has three butyric acid residues. The kit also demonstrates dehydration synthesis and hydrolysis, mono- and polyunsaturated fatty acids, the nature of a soap, the nature and function of phospholipids, and, using all the carbon atoms, longer chain fatty acids
