Tuesday - DNA extraction and Beginning Translation

Today we did the Strawberry DNA extraction. You should be able to answer the questions below!

1. What are the following used for?
             Strawberry (why can't we use another fruit?)
             Soap/Salt
             Ethanol

2. How is DNA organized in the Cell?

3. Why does the DNA tangle when we remove it from the nucleus?

Here is good video describing the experiment!



We also started discussing translation. In your groups you came up with a starting list of the process. Try to answer the questions below

1. What are the main molecules involved in translation?
2. What is mRNA translated into?
3. What are the building blocks of that molecule?
4. What are codons and anticodons?

If you did not like the crashcourse video here are a couple more!
