Today's blog post was written for us by one of Susan Phillips AP biology students. We hope you enjoy it along with the free DNA Model Activity.
Have you ever been confused by the endless patterns of Deoxyribose Nucleic Acid? Me
too. Which purines and which pyrimidines bind together? How does this structure
affect the replication of DNA and the Semi Conservative model? How does this
shape affect RNA synthesis, protein synthesis and the laws of inheritance? Perhaps
these questions seem terribly complex at the moment, but with a little
diligence this quick lab will cement the structure of DNA into your student’s
With simple materials, students can creatively make their own DNA replicas and enjoy
a tedious, yet core topic in biology. This project will display the patterns of
guanine, adenine, thymine and cytosine. Without a base knowledge of DNA your
students may struggle with future topics and more complicated subjects. This
project may spark discussions concerning the relation of genes and DNA, and
will invite an amiable view of an otherwise route conversation. This visual aid
may assist in the students’ memory and provide a positive outlook on the rest
of the unit.
