Definition
| Replication goes from 3' to 5' and constructs new strand from 5' to 3'. |

|
Term
|
Definition
| Points at were replication begins. |

Term
| Single-Strand Binding Protein |
|
Definition
| Prevents DNA strands from rejoining. |
|
|
Term
| DNA-Polymerase III (DNApol III) |
|
Definition
| Constructs new DNA strand. Can only add nucleotides to an existing strand. Proof-reads inserted bases. |
|
|
Term
|
Definition
| Constructs RNA primed to which DNApol III can add nucleotides. |
|
|
Term
|
Definition
| 3' - 5' constructed continuously. |
|
|
Term
|
Definition
| Requires extra RNA primers for construction and is constructed in fragments (known as Okazaki fragments). |
|
|
Term
|
Definition
| Replaces RNA primers with DNA. |
|
|
Term
|
Definition
| Joins DNA fragments together. |

|
Term
| Differences Between Prokaryotic and Eucaryotic Replication |
|
Definition
| Prokaryotes have mitple origins of replication, Pol α creates new strand, Pol β replaces RNA primers with DNA. |
|
|
Term
|
Definition
| Check and remove incorrect bases from DNA (polymerase then inserts correct bases). |
|
|
Term
|
Definition
| Part of DNA is cut out and replaced (such as thymine dimers caused by UV light). |
|
|
Term
| Polymerase Chain Reaction (PCR) |
|
Definition
| Method of replicating DNA in the lab by separating it with heat and then adding DNApol and bases (this sequence is repeated as many times as needed). |
