| 9291684386 | DNA Replication | The process in which DNA makes a duplicate copy of itself. |  | 0 |
| 9291684387 | Helicase | An enzyme that unwinds the double helix of DNA and separates the DNA strands in preparation for DNA replication. |  | 1 |
| 9291684388 | DNA Polymerase | Enzyme involved in DNA replication that joins individual complementary nucleotides to produce a duplicated DNA molecule. |  | 2 |
| 9291684389 | Semi-Conservative Replication | In each new DNA double helix, one strand is from the original molecule, and one strand is new. |  | 3 |
| 9291722122 | 5' | End of a new DNA strand that is formed first during replication. | 4 | |
| 9291722123 | 3' | In transcription, nucleotides are always added to the _____end of the elongating strand. | 5 | |
| 9291738933 | Replication Bubble | Region of DNA, in front of the replication fork, where helicase has unwound the double helix |  | 6 |
| 9291753249 | DNA Primase | Synthesizes a short RNA primer to allow DNA Polymerase to begin during replication |  | 7 |
| 9291759606 | DNA Ligase | Enzyme that eventually joins the sugar-phosphate backbones of the Okazaki fragments | | 8 |
| 9291763188 | Leading Strand | The DNA strand that is synthesized continuously during replication | 9 | |
| 9291765914 | Lagging Strand | In DNA replication, the daughter strand that is synthesized in discontinuous stretches called Okazaki fragments |  | 10 |
| 9291775658 | Okazaki Fragments | Relatively short fragment of DNA synthesized on the lagging strand during DNA replication. | | 11 |
| 9291778295 | Mismatch Repair | Enzymes remove and replace incorrectly paired nucleotides that have resulted from replication errors | 12 | |
| 9291782089 | Nucleotide Excision Repair | A nuclease cuts out and replaces damaged stretches of DNA; can be used to fix mutations |  | 13 |
