DNA Replication Models

Today in Bio, we’ll be starting our work on our Replication Models. They are great visuals of how the process of replication actually looks. In order to complete the model you will need the following:

dnahelicaseThis is a large undertaking and will take us a few days to complete. To keep track of our progress there are checkpoints listed in the directions as well as a photo journal to keep. The photo journal should include several pictures of you and your group working as well as a description of what is taking place on your model.

When you are finished, you will hang your model somewhere in the school building for all to see. Then snap a picture of it hung up and email it to me, along with your completed photo journal, at jkubuske@gocathedral.com

If you need a refresher of how DNA replication works, here are the notes from the other day. Have fun and good luck!

The DNA (web quest) Puzzle

Today we’ll begin our long journey through the amazing world of DNA.
As we begin to look forward to a fun filled few weeks, its at this point that we look back into the past and discuss the important people who’s contributions and life’s work answered some of life’s biggest questions.

If you are using Puffin: Go to http://www.DNAi.org and click timeline, there you will a see a list of scientists broken up by decade. Use the web quest to determine which scientists to look up. You can read their biographies by clicking their picture. You can also have them tell you their story by clicking the animated icons above them.

If you are not using Puffin: Below are videos that are taken from the website DNAi.org. Use them to complete the introduction to these scientists as a part of this webquest (PDF).

  • Friedrich MeischerBio
  • Erwin Chargaff – Bio
  • Rosalind Franklin – Bio
  • Alfred Hershey & Martha Chase – Bio
  • James Watson & Francis Crick Bio

Together the contributions come together to fit like pieces of a puzzle (Read Here) and the shape of the DNA molecule was finally uncovered.
