Bacteria chemical communication: warnings of toxic issues (Introduction)

QUOTE: Since the repair process is completed within 1-2 hours after modification of the RNA, the researchers believe that the cell is already 'prepared' to deal with the damage. It is conceivable that the sulfur-containing RNA bases act as scavengers of free methyl groups that are produced as a direct result of stress, thus preventing them from modifying the DNA or other proteins. Since bacterial cells are full of RNA molecules, these could function as an efficient detoxification mechanism to mop up reactive chemical groups." (David’s bold)

DAVID: this shows how bacteria are programmed to handle stress in an automatic fashion with pre-existing protein complexes.

DAVID (second post about bacteria): No thinking on the part of the enterococcus. Just automatically deploy the protein molecules

dhw: Once a problem has been solved, the solution will be passed on. Please explain why NEW drugs kill millions of bacteria until eventually a solution is found. If all cells were “prepared” to deal with the damage, why do so many die?

We have discussed over and over the many way bacteria develop resistance with new antibiotics. In this study the bacteria were already prepared. That is what I said in comment.
