Question
Chapter 14, Problem 3MC
Summary Introduction
Introduction: Genetic engineering or recombinant DNA technology is the technique, which involves modification or manipulation of genes of a crop or an organism. The genetically modified crops that include gene transfer from another species are called as transgenic crops.

Students have asked these similar questions
A majority of genetically engineered crops in production worldwide today have been engineered with a gene that:
A) codes for a protein that improves the nutrient value of the food
B) codes for a protein which makes the crop resistant to the herbicide Roundup
C) codes for a protein that allows the plant to thrive in a high-salt environment
D) codes for a protein that suppresses the production of allergens in the food
Many people are opposed to the production of transgenic crop plants. Do you feel that position is justified?
A farmer is attending a genetic conference on crops. What is the best question a farmer could ask before deciding to use genetically modified crops or non-genetically modified crops?
A. Are genetically modified crops typically safer?
B.Are genetically modified crops typically more productive?
C.Are genetically modified crops typically more controversial?
D.Are genetically modified crops typically more expensive?
