Scientists engineer safe, virus-resistant E coli for research

Drug Discovery World

In a step forward for genetic engineering and synthetic biology, US researchers have modified E coli bacteria to be immune to infection by all natural viruses tested so far. The team used two safeguard methods to prevent the bacteria and their modified genes from escaping into the wild.

Gene Switch: A Novel Platform for Switching Genes On and Off

Roots Analysis

coli bacteria, as well as lambda bacteriophage, can adapt to the alterations in the composition of their nutrient medium. Further, the expression of any gene is dependent on the rate at which it is transcribed into mRNA and translated into proteins. When activator binds to the operon, it either speeds up or permits gene expression.
