Microbial Genetics Why Deinococcus radiodurans is able to survive massive exposure to radiation? Because it has unique DNA repair mechanisms Because its cellwall contains radioactive elements Because it produces a thick shell which acts as a shield from the radiation Because it has many copies of genes encoding DNA repair Because it has unique DNA repair mechanisms Because its cellwall contains radioactive elements Because it produces a thick shell which acts as a shield from the radiation Because it has many copies of genes encoding DNA repair ANSWER DOWNLOAD EXAMIANS APP
Microbial Genetics Why the bacterium Treponema pallidum is difficult to culture? Because it requires extremely low temperature at which water freezes 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 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 ANSWER DOWNLOAD EXAMIANS APP
