Genetically modified organisms in agriculture — practice question
Genetic engineering is a contemporary way of producing crop plants with better characteristics. One crop example with better characteristics is soybean, Glycine max, which has been genetically modified so that it is resistant to a herbicide. This genetically modified soybean is known as GM soybean. To produce GM soybean, a bacterial gene together with a section of regulatory DNA were inserted into soybean cells.
(a)[5]
Outline the functions of enzymes and a section of regulatory DNA in the making of genetically modified organisms such as GM soybean.
(b)[2]
In 2018, 123.5 million hectares of land worldwide were used to grow soybean crops. GM soybean occupied 73% of this area. Also in 2018, soybeans made up 50% of the total GM crop area worldwide. Calculate the total area used to grow GM crops worldwide in 2018. Show your working.
(c)[4]
Discuss the social consequences of growing GM crops.
