| Question | Answer |
|---|---|
| When does DNA take place? | When cells divide |
| What happens to the DNA double Helix? | It unwinds from one end and the two strands split apart |
| What bonds are broken during this process? | Hydrogen Bonds between the complementary bases |
| What substance line up along side each DNA strand to produce a copy? | DNA nucleotides |
| What bonds are formed between the original bases and the new DNA nucleotide bases? | Hydrogen Bonds |
| What is formed? | Two complete strands of DNA |
| What is this process known as? | Semi-conservative |
| What is the theory of conservative replication? | This is where one DNA molecules has the two original DNA strands, and the other molecule has two new DNA strands |
| What is the theory of Fragmentary replication? | All the DNA strands are made up from a mixture of both old and new |
| What scientists proved the semi-conservative replication theory? | Meselson and Stahl |
