What is Genetic Engineering? Scientists use genetic engineering to manipulate, recombine and change genes.

What is Genetic Engineering? Scientists use genetic engineering to manipulate, recombine and change genes. Genetic engineering can be used to: – make large amounts of hormones such as insulin – improve crops (vegetables, wheat etc. ) – research genes and diseases

Controversies Some groups have argued that genetic engineering is wrong and is "doing the work of God", but most scientists believe that genetic engineering is essential to help future medical discoveries.
