As you can see from the "Activity" part of this week's assignment, the Internet, as well as your textbook, provides an enormous amount of interesting and useful information on genetic engineering and biotechnology products. Activity Assignment 2 requires you to research genetically engineered animals on the Internet as biotechnology products using the suggestions in the activity assignment file (pdf) or other sources you locate on your own, and post your findings/opinion to the Discussion Forum by 8 pm Wednesday of the assignment week (earn 10 activity points). The Discussion Assignment is to provide a thoughtful response by 8 pm Sunday of the assignment week, to the information posted by two other students on this topic (earn 10 discussion points). You should include in your responses to both assignments, sufficient information on your Internet sources for other students to find what you read. When referencing a web site in a document or a posting to a discussion forum, be sure to include the web address, the author of the page (if known), and the date when you accessed the site or when the site was last updated. Remember, your response to another student should address one or more technical aspects of their original posting, and not simply agree or disagree with their statements.
