chapter 7 - applying biotechnology

Question 1

Explain how recombinant DNA technology can be used in agriculture to create a GMO for human benefit

Question 2

Name an example of recombinant crops/organisms that are: resistant to pests and herbicides, have a faster growth rate, greater product quality and yield

Answer 2

Bt Cotton is resistant to the helicoverpa worm, the Bt protein was inserted so that when the helicoverpa worm ingests a small portion of the cotton plant, the protein will attack the worm’s digestive system and kill it

Round up Ready Canola is resistant against glyphosate meaning the glyphosate only affects the weeds growing in the crop, leaving the canola unaffected and producing an increased yield compared to regular canola.

Question 3

Name an example of how recombinant DNA can improve a crop/organism’s tolerance to adverse environmental conditions

Question 4

Explain how recombinant DNA technology can be used in environmental conservation using an example

Question 5

Explain how DNA identification technologies can be used in environmental conservation such as assessing gene pools

Question 6

What are some possible adverse effects of transgenic organisms on genetic diversity

Question 7

What are some possible adverse effects of transgenic organisms on the environment

Question 8

Explain the possible adverse side effects of using transgenic organisms on non-target species

Question 9

Argue for the use of GMOs in agriculture using examples

Question 10

Argue against the use of GMOs in agriculture using examples
