2. How do the nitrogenous bases pair? pairs with pairs with 3. If a strand of DNA has 20% C, what percent will be G?

4. If a strand of DNA has 35% A, what percent will be T? 5. If a strand of DNA has 10% G, what percent will be T?

5. List three facts about the structure of DNA

2. Adenine pairs with Thymine and Guanine pairs with cytosine!
3. C and G pairs together, if you think about it, you need to have exactly the same amount of both. So if you hade 40% of cytosine you would have 40% of guanine, if you had 30% of cytosine you would have 30% of guanine so if you have 20% of cytosine you would have ___ of guanine
4. I’m pretty sure with information above you can figure this one out !
Hope this helps!
