Revolutions and Human Survival"
This week is all about
introducing you to the science behind nature. For your primary post, select ONE
of the following discussion topics. Using your own words, write a primary post
that addresses each question.
Your primary post is
worth 24.5 out of 35 points. The remaining points are earned by replying to at
least one of your classmates. You don’t need to use any sources other than the
ones specified, but if you do use other sources, be sure to cite them.

Discussion "Inheritance and Genetic Engineering" Please respond to
the following: Note: Online students, please respond to one (1) of the
following four (4) bulleted items. • Compare and contrast the Mendelian and
non-Mendelian patterns of inheritance. Describe what you believe is the most
significant difference, and explain why. • In 1918, an influenza pandemic that
originated with avian flu killed 50 million people. Researchers isolated
samples of that virus from bodies of infected people preserved in Alaskan permafrost
since 1918. From the samples, they sequenced the viral genome, and then
reconstructed the virus. The reconstructed virus is 39,000 times more
infectious than modern influenza strains, and 100 percent lethal in mice.
Understanding how this virus works can help us defend ourselves against other
deadly influenza strains that arise. For example, discovering what makes it so
infectious would help researchers design more effective vaccines. Consider this
statement: Critics of the research are concerned that if the virus escapes the
containment facilities (even though it has not done so yet), it might cause
another pandemic. Worse, terrorists could use the published DNA sequence and
methods to make the virus for horrific purposes. Determine whether or not you believe
this research makes us more or less safe, and explain why. Propose at least one
(1) other application these discoveries could be used for. • Go to one (1) of
the Websites below to read the article of your choice. Discuss the main point
of the article you chose to read. Determine at least three (3) benefits of the
genetically modified organism(s) described in the article. Give your opinion
about what risks the genetically modified organisms pose to society, and
justify how non-scientist citizens can arrive at an informed opinion in such
matters. -"Synthetic Life: the Revolution Begins" -"Engineering
