DNA

1. What is DNA?
   Deoxyribonucleic Acid
   

2. What are the 4 bases?
   A for adenine, T for thymine, C for cytosine and finally G for guanine, so the bases are ATCG.
   

3. What 2 pieces of information did the scientists need to solve the elusive structure of DNA?
   Phosphate backbone was on the outside with bases on the inside, the molecule was a double helix
   

4. What are the specific base pairs?
   A & T, G & C
   

5. How does the pairing rule affect the shape and structure of DNA?
   A&T makes a 2 hydrogen bond and G&C makes a 3 hydrogen bond, which directs the structure and shape of the DNA molecule when its being copied.
   

6. What does the DNA do during cell division?
   It is copied.
   

7. How many base pairs does E. Coli have? How long does it take to replicate? How is the DNA packaged in the cell?
   It has 4,639,221 base pairs, takes 40 minutes to replicate, and it’s inside the genetic makeup of the cell.
   

8. How many base pairs does Human DNA have? How long does it take to replicate? How is the DNA packaged in the cell?
   Humans have3 billion and more base pairs, they take 12 to 24 hours, and it is packaged in the nucleus.
