What are "resistance genes"? Resistance to what? This describes mechanisms of action of various antibiotics. Linkname: Antibiotics URL http://users.erols.com/jkimball.ma.u...tibiotics.html size: 441 lines Resistance genes give a bacteria a pathway to outwit that sort of mechanism. When a biotechnologist is trying to genetically engineer a species they usually put an antibiotic resistance marker in the package. That is so they can find out which of the plants have been changed. The changed ones will not die when the antibiotic is applied. Another marker option for the job is to make the organism fluoresce green. Bacteria are mutating constantly. Yes they transfer genes between one another and pick them up from dead ones, too. And antiobiotic restance genes, if available, can allow the bacteria to become resistant to other antiobiotics, too. |
