1. DNA is a type of polymer. Polymers are created by
joining monomers together
What are the monomers of both DNA and RNA called?
What is the difference between these two monomers?
2. The “backbone” of DNA is made up of two
alternating components, what are the two components?

3. In DNA, the base _______________________ pairs with
_______________________ and the base _______________________ pairs with
_______________________ .
4. In RNA, the base _______________________ pairs with
_______________________ and the base _______________________ pairs with
_______________________ .
This is called complementary base pairs. Thus one strand of DNA is complementary to the other
strand (opposite/matching).
5 Describe how the types of bonds involved in a molecule of DNA. What type of bond holds two strands
together? What type of bond holds nucleotides within the same strand together?
