| What is the Watson/Crick model? |
|
Definition
| The model was built to fit the pertinent biochemical rules and insight. They discovered the double helix structure of a DNA molecule. |
|
|
Term
|
Definition
| How the molecule of inheritance is duplicated before the cell divides. |
|
|
Term
| What happens in DNA replication? |
|
Definition
| An organism uses replication enzymes in which pry apart hydrogen bonds. The double helix opens up and unwinds making it a new strand. |
|
|
Term
|
Definition
| Catalyzes formation of the two new DNA strands from free nucleotides. |

Term
| How can genetic variation occur? |
|
Definition
| Random or independent orientation during metaphase 1 or CROSSING OVER |
