1, transgenic corn is a genetic engineering transformation of a specific corn strain through modern molecular biology technology; However, ordinary corn does not use genetic biological modification technology.

2. Ordinary corn does not contain any genetically modified ingredients.

3. Genetically modified foods are mainly controversial about health, environment, ethics and national security; Conventional corn is threatened by external threats such as pests and diseases.

Transgenic corn is the use of modern molecular biotechnology to introduce the genes of plants with distant species and useful species into the corn genetic material that needs to be improved, and to make its offspring reflect the corn with stable genetic traits that people pursue. Generally speaking, genetically modified corn is the result of concentrating the advantages of other corn on one kind of corn.

Characteristics of transgenic corn: if the appearance is distinguished, the corn with insect-resistant gene is large, shiny, uniform in size, neat and beautiful, and has no insect eyes. At present, transgenic corn is transformed with bt protein gene, which can make corn express bt protein and produce insect-resistant effect. The protein will not change the appearance and other characteristics of corn, so the appearance of transgenic corn and ordinary corn is the same, which can not be distinguished by naked eyes. If you want to effectively distinguish whether it is genetically modified corn or not, you can distinguish it through experiments or molecular analysis.
