Fantastic voyage: Research: How bacteria becomes resistant to antibiotics ?

  • RNA means:
Ribonucleic acid, a nucleic acid present in all living cells. It principal role to act as a carrying instructions  from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.  

  • Development of resistance  - Higher tier
The main step in the development of resistance are :
  1. Antibiotics kill individual pathogens of the non resistant strain
  2. Resistant individual pathogens survive and reproduce
  3. The population of the resistant pathogens increases.

The rate of development of resistant of bacteria can be slowed down. One way to do this is to avoid using antibiotics for infections that are not serious, such as mild throat infections. 

  • As you might think bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they can't effective against viruses. 

Giving antibiotic for virus do not work and can resistance if over used but GP are sometimes under pressure by patient to hand over antibiotic.

  1. Good stuff Dinesh - now have a go at sketching how you think this cycle might look.(Don't worry about designing the 'characters' of the cells/antibiotics etc, just show that you can picture how the cycle works)
