#BioDub Candy DNA

1/6/2017

 
Students used candy to model the structure of DNA. They were expected to create an assigned sequence of DNA nucleotides and then likewise create the complimentary DNA strand.

In DNA, each nucleotide consists of a deoxyribose (red licorice), a phosphate (marshmallow), and a nitrogenous base (Skittle). It is important that the deoxyribose and phosphates make up the back-bone and that the bases are bound to the deoxyribose.

The Skittle bases are as follows:
  • Thymine (T) - Purple
  • Adenine (A) - Red
  • Guanine (G) - Green
  • Cytosine (C) - Yellow

Based on the original stand of DNA, the complimentary strand of DNA was created using the correct base pairs: G to C, C to G, T to A, A to T.

The original DNA strand was glued in place for a later activity (transcription).
