| 1245471045 | Transformation | Incorporation of naked DNA into a bacteria cell. | 0 | |
| 1245471046 | Chargraff's Rule | Adenine to Thymine amount is proportional Cytosine to Guanine amounts and are proportional in a cell of an organism. | 1 | |
| 1245471047 | origins of replication | where DNA replication begins. | 2 | |
| 1245471048 | How do eukaryotic chromosome replication origins differ from prokaryotic? | Eukaryotic may have hundreds or even thousands of replication origins, compared to single origin site for prokaryotes. | 3 | |
| 1245471049 | What is the function of helicase? | Unwinds DNA during DNA replication. | 4 | |
| 1245471050 | What is the function of Single Stand Binding Protein? | Binds to and stabilizes unwound DNA during DNA replication. | 5 | |
| 1245471051 | What is the function of topoisomerase? | Corrects for overwinding and high tension at the replication fork during DNA unzipping. | 6 | |
| 1245471052 | What is the function of Primase? | Primase is an enzyme that makes RNA primers that attach to the 5 prime end of the leading strand and lagging strand. | 7 | |
| 1245471053 | What is the function of DNA polymerase 3? | It adds nucleotides to the 3 prime end of the RNA primer during DNA replication in leading and lagging strands. | 8 | |
| 1245471054 | What is the function of DNA polymerase 1? | It removes RNA primers and replaces them with DNA on the 3 prime end of leading and lagging strands. | 9 | |
| 1245471055 | What is the function of ligase? | Ligase is an enzyme that joins DNA strand that replaced the RNA primer to the rest of the strand, in both the leading and lagging strand. | 10 | |
| 1245471056 | Name 3 DNA repair mechanisms. | 1) DNA Proof reading - finds errors and corrects them as "it" moves along the strand. 2) Mismatch repair - finds matching errors, cuts out the mismatched section and DNA pol I comes in and inserts a new corrected sequence of DNA. 3) Excision repair - finds non functional damaged DNA and excises it, then DNA pol I inserts the correct DNA base sequence in 5 prime to 3 prime direction. | 11 | |
| 1245471057 | What is the function of telomerase? | Telomerase catalyzes the lengthening of telomeres in cells, and provides 3 prime O H hydroxyl to the RNA primer, making it serve as a template for laying down more DNA nucleotides to restore the original length of the DNA strand. | 12 |
