ii. Bacteria and Genetic Engineering

What are PLASMIDS?

  • Extra chromosomal circular pieces of DNA in bacteria that normally carry genes such as:

  • R genes : Resistance to antibiotic genes,

  • TOX genes: Toxic genes (poisons)

  • F Factors : Fertility factors (Sex factors)

  • Plasmids are the vehicles of Genetic Engineering
