DNA Structure

These questions can be completed on paper or on your blog.  Use the information on your colouring sheet to answer them.

1.  What are the three parts of a nucleotide?
2.  What are the 4 bases that are found in DNA?
3.  What 2 molecules make the "sides" of the DNA ladder?
4.  What molecules make up the "steps" or "rungs" of the ladder?
5.  Which molecule do the bases attach to on the sides?
6.  Which bases are always paired together?

Once your colouring and questions are completed you will be making a DNA model with the following supplies:  straws, marshmallows & toothpicks.

Create your model and either label or make a legend of the following parts:

• bases (A,C,T,G)
• phosphate
• sugar
• hydrogen bonds

Post this to your blog (a picture of your model with the legend)
