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 none of these E. coli has acquired many genes via horizontal transfer E, coli has lost approximately 50% of its genome there has been little change in either genome none of these E. coli has acquired many genes via horizontal transfer E, coli has lost approximately 50% of its genome there has been little change in either genome ANSWER DOWNLOAD EXAMIANS APP
