|
Definition
|
|
Term
| What do A and G bases do and what do they look like? |
|
Definition
| They have two intertwined hoops that like to pair with the bases of Pyrimidines. |

|
Term
| What do T and C bases do and what do they have? |
|
Definition
| They pair with Purines and have only one loop. |
|
|
Term
| What does A always pair with? What about G? |

|
|
Term
| What is the Backbone made of? |
|
Definition
| It is made of two molecules, which are 5 Carbon sugars called Dioxyribos, and a phosphate group. |
|
|
Term
|
Definition
| a series of phosphates. The bases are Nitrogen, which is the main molecule, and together they are Nucleic Acids. |

| What are the three steps to DNA replication? |
|
Definition
| 1.Unzip 2.Add New 3.Put back together |
|
|
Term
| What does DNA Replication need help from? |
|
Definition
|
|
Term
| Elaborate on the "Unzip" step: |
|
Definition
| The enzyme that helps unzip is DNA Helicase in order to undo the Double Helix. |
|
|
Term
|
Definition
| DNA Polymerase trails the enzyme, adding complementary bases. |
|
|
Term
| Elaborate on "Put Back Together": |
|
Definition
| Ends up making 2 separate but identical molecules. |
|
|
Term
|
Definition
| It stands for Nanometer. It is 10 to the -9th power. |
|
|
Term
| When and where does a double helix split, and why? |
|
Definition
| A double helix splits in a few different places that end up meeting in the middle because it is a very diverse molecule, esp. because it is Eucaryotic. |
|
|
Term
| Describe Prokaryotic DNA splitting. |
|
Definition
| It looks like a ring and is not as diverse. Prokaryotes begin at one point and has 2 replication points. |
|
|
Term
| What is the extra RNA base? |
|
Definition
| Uracil, which is a pyrimidine. |
|
|
Term
|
Definition
| It is single sided and has a long, linear shape. |
