APES Activity Understanding Crop Genetic Engineering


Everyone should understand a general description of the overall process of
genetic engineering. A basic explanation of the five steps for genetically
engineering a crop is described in a guided animatio
n at

.



The five steps are:

1.

Locating an organism with a specific trait and extracting its DNA.

2.

Cloning a gene that con
trols the trait.

3.

Designing a gene to express in a specific way.

4.

Transformation, inserting the gene into the cells of a crop plant.

5.

Plant breeding to get the transgene into an elite background.

1.

Access the website and choose
Overview

in the selection menu.

2.

Choose the Animation link under the menu.

3.

Play the animation


Overview of Crop Engineering

4.

Use the information of this animation to answer the questions below.

5.

Now that you understand the basics of genetic crop engineering play the
animation “
Who Wants To

Be a Genetic Engineer


6.

Begin with the Creation of Cinna
-
Apples to test your knowledge of the GE
process.

7.

Apply these skills now to write and explain in your own words the steps
you used to create Monsanto’s famous Bt Corn.

At the completion of this lesson
, you should be able to:



Define genetic engineering.



List and briefly explain the five basic steps in genetic engineering.
Describe why each is necessary.



Identify the fundamental differences between genetically engineered crops
and non
-
genetically enginee
red crops.



Explain the limitations to traditional breeding that are overcome by genetic
engineering.



Identify the approximate length of time required to obtain a marketable
transgenic crop line (complete the entire crop genetic engineering
process).
