Read the animation page by page – just click the “next” button when you are ready to move on.

1.    How does the mRNA leave the nucleus?

2.    Is just one mRNA molecule made?  Explain.

3.    How many amino acids does each codon code for?

4.    Describe the structure of a tRNA molecule.

5.    Where does the energy to form the peptide bond between two amino acids come from?

6.    Can a single mRNA be read more than once?  Explain.

Click on “Play DNA Game arrow in the picture”;  Click “next” and reading each page, continue to click next until you come to the game.;   Click on organism #1 and match the base pairs as fast as you can!   It is hard. 

Click Next and then click on each organism until you identify the one that belongs to chromosome #1;   continue playing the game with the other two chromosomes, filling in the chart below.

Be careful, other teams may get different results.

Chromosome #	How many chromosomes?	How many base pairs?	How many genes?	What is the organism?

DNA Mutations

Today we will be doing an activity on BrainPop about mutations.  Click on this link.  Please speak to one of the faculty to get logged in with an ID and password.  Then you will then view the animation.  After the animation do the quiz.  Please do it in the review mode first.  Then, if you like, you can score it for yourself.

When you are done with this activity you can:

•  look at any of the other activities for mutations.
• View any of the other animations on the BrainPop site, in any subject.
• Do the DNA replication matching game.  Click this link to go there.
