Question

The crops engineered for glyphosate are resistant/ tolerant to
A. Insects
B.Herbicides
C.Fungi
D.Bacteria

Answer 1

Glyphosate: IUPAC name of glyphosate is N-(phosphonomethyl) glycine.
It is an organophosphorus compound, basically having a phosphonate, which inhibits the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase.

Complete answer: A genetically engineered crop that contains glyphosate. It is made for tolerating herbicides because it interferes with many metabolic processes in plants and also in animals and it disrupts the balance of bacteria present in the gut. It damages DNA and leads to cancer. This genetic modification of crops protects the desired crops from unwanted chemical herbicides which otherwise are harmful. Some of the benefits of genetic engineering include:
1. More nutritious food.
2. Food will be tastier Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) less use of pesticides.
3. Increased supply of food with reduced cost with longer shelf life.
4. Plants and animals which grow fast.
So, the correct option is option B.

Note: Genetically engineered crops were first introduced in the U.S. in the mid-1990s. Most current genetically modified crops grown in the U.S. are engineered for insect resistance or herbicide tolerance. Corn, soybeans, and cotton are the 3 largest acreage GM crops. GM crops grown in Colorado include corn, alfalfa, sugar beet, soybeans, etc.
