Well its easy the Bt gene is inserted into one plant cell by using a bacterial plasma.
Bio refers to study of living things + technology (is pretty straightforward- i dont think i need to explain this)
This means Vincent modifies the DNA of bacteria to study the function of their genes is the correct answer :)
Leukopenia means a low count of white blood cells in the body. When there is a low white blood cell count in the body, and in particular a low level of neutrophils (a kind of white blood cell that fights infection), there is quite a significant risk of developing an infection, and once an infection is developed and the white blood cell count is low, the body will not be able to protect itself and fight off the infection. In severe cases , infection may lead to death.
