Question 1 |
Why Deinococcus radiodurans is able to survive massive exposure to radiation?
Because it produces a thick shell which acts as a shield from the radiation | |
Because it has unique DNA repair mechanisms | |
Because its cellwall contains radioactive elements | |
Because it has many copies of genes encoding DNA repair |
Question 2 |

250-350 genes | |
1000-1500 genes | |
1500-2000 genes |
Question 4 |
Why the bacterium Treponema pallidum is difficult to culture?
Because it requires a great deal of water to reproduce | |
Because it is unable to use carbohydrates as an energy source | |
Because it lacks the genes needed for TCA cycle and oxidative phosphorylation | |
Because it requires extremely low temperature at which water freezes |
