MOLE INHERITANCE
| Question | Answer |
|---|---|
| Bacteriophages | Viruses the infected bacteria |
| Antiparallel dna structure | two phosphate groups run in opposite direction |
| what are the three hypothesis for DNA replication | Conservative Semiconservative disperse |
| what is the semiconservative model? | new strands remains are attached to their templates strands and then break off to from new templates. |
| Origin of Replication | the replication of DNA starts at the origine of replication |
| replication fork | a y-shape region where the DNA stands are being unwind. |
| Helicases | enzymes that untiwst the double helix DNA stands |
| Signal strand binding protein | Binds to the unpaired DNA strands keeping them from re-paring |
| Topoisomerase | relieves the strains cause by unwinding |
| RNA primer | the RNA strand, start of the new strand formation |
| Primase | synthesize RNA primers unding parental DNA as a template |
| DNA polymerases works for what end of the template to the other? | 3' to 5' |
| leading strands | new strand being developed by DNA pol 3 breaking from 3' to 5' direction |
| Lagging strand | new stand being developed by DNA pol 3 breaking from 5' to 3' (okazaki fragment) |
| okazaki fragment | lagging strand is synthesized discontinually, series of segment |
| DNA ligase | Finish the last sugar phosphate backbone of all the okazaki fragment |
| mismatch repairs | enzymes remove, repair, and/or replace incorrect paired neucleotide that have resulted from replication errors. |
| Nuclease | enzymes that cuts out damage strands |
| nucleotide excision repair | DNA repairs system |
