Its the most wonderful time of the year…

Christmas time + Finals Week =

Here is the Biology Study Guide Key . Below is all of the YouTube videos from this semester as a playlist. You can skip past the stuff you’re good on and go on to the next. Good luck!

Making Monsters

Thats right, today in class we will be making monsters based on their DNA code.

First make sure you get BOTH hand outs from the table up front. Then follow the directions on the front page to draw the Monsters on the back page. Here’s what you do:

  1. Use the DNA code to match the mRNA compliments. (Remember: T→A but A→U)
  2. Use the mRNA to match the tRNA compliments.
    1. You can check your work by comparing the tRNA to the DNA; they should be identical except that the ‘T’s have become ‘U’s.
  3. Use the chart at the bottom of the page to determine what amino acid (#) is coded for by each mRNA Codon. Write the number in the Amino Acid section.
  4. Repeat this process for all mRNA codons.
  5. Use the Amino Acid sequence to determine what trait has been coded for by the DNA.
  6. Once all traits have been decoded, draw your MONSTER! Give him/her a name and add any other traits you want including the ones coded by the DNA. The drawings should be neat and colored.
  7. Finally, write down the FULL sequence of DNA from the original DNA provided, as well as the list of traits.

There You Go! That’s how easy it is to make a monster… sort of. Either way, this is great practice doing transcription and translation which are the two steps of Protein Synthesis. So have fun and I’ll see you again soon!

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

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 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 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.
