Mitosis
BIOL 1113 review 3
| Question | Answer |
|---|---|
| DNA synthesis (transcription) moves from | 5' to 3' |
| Lagging strands are the (blank) strand and lag because DNA polymerase can only move from 5' to 3' | 3' to 5' |
| DNA polymerase has to move up on the lagging strand and move backwards to make | okazaki fragments |
| helicase | enzyme that unwinds and separates DNA for polymerase to copy |
| eukaryotic cells spend most of their time and energy in interphase and (blank) | mitosis |
| G1 interphase | growth |
| G2 interphase | more growth and preparation after S phase |
| S interphase | chromosome replication |
| G0 (g naught) | cell is performing function without replication |
| angiogenesis | development of blood vessels |
| telomerase | extends telomeres so cells can continuously divide |
| sister chromatid | identical copies in chromosome |
| ligase | enzyme that binds okazaki fragments together |
| cancer cell oncogenes are | activated |
| cancer cell tumor suppressors are | deactivated |
| nondisjunction | inability of cell to evenly do anaphase |
| crossing over | ends of chromosomes swap genetic information |
| germ cells are found in | testes and ovaries |
| crossing over can only occur in | meiosis |
