BOTANY

Detailed explanation-1: -Most GMO corn is created to resist insect pests or tolerate herbicides.

Detailed explanation-2: -Another benefit of Bt maize is reduced occurrence of ear molds (Figure 1b). Because insect damage provides a site for infection by molds, Bt-protected maize can have lower levels of toxins produced by molds (i.e., mycotoxins), especially fumonisin and deoxynivalenol (Dowd 2000, Munkvold et al.

Detailed explanation-3: -The world’s most widely planted GM crops, including soybean, corn, and cotton, were created with a few relatively simple genetic tweaks. By adding a single gene from bacteria to certain crop varieties, for example, scientists gave them the ability to make a protein that kills many kinds of insects.

Detailed explanation-4: -Most of the GMO crops grown today were developed to help farmers prevent crop and food loss and control weeds. The three most common traits found in GMO crops are: Resistance to certain damaging insects. Tolerance of certain herbicides used to control weeds.

Detailed explanation-5: -By inserting the Bt gene into the DNA of the corn plant, scientists gave it the insect-resistance trait. This new trait does not change the other existing traits. In the laboratory, scientists grow the new corn plant to ensure it has adopted the desired trait (insect resistance).
