Microbial Genetics Why the bacterium Treponema pallidum is difficult to culture? 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 Because it requires extremely low temperature at which water freezes Because it requires a great deal of water to reproduce ANSWER DOWNLOAD EXAMIANS APP

Microbial Genetics Why Deinococcus radiodurans is able to survive massive exposure to radiation? Because its cellwall contains radioactive elements Because it has many copies of genes encoding DNA repair 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 Because it produces a thick shell which acts as a shield from the radiation Because it has unique DNA repair mechanisms ANSWER DOWNLOAD EXAMIANS APP
Microbial Genetics In the time since E. coli and Salmonella diverged evolutionarily E. coli has acquired many genes via horizontal transfer none of these there has been little change in either genome E, coli has lost approximately 50% of its genome E. coli has acquired many genes via horizontal transfer none of these there has been little change in either genome E, coli has lost approximately 50% of its genome ANSWER DOWNLOAD EXAMIANS APP
