Lab procedure
Answer key
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.
