What about cloning and the genetic code?

There is a universal nature to the genetic code – evidence that helps us understand how humans are part of an overall web of life on earth. Since variation occurs during meiosis, this is when errors in the copying of genetic material can create major shifts. The evolutionary significance of meiosis can be illustrated by examples of genetic variation that result from a failure of the meiotic process.

Watch these two video clips to understand the important distinction between the process of mitosis and meiosis:

Now consider a situation where the genetic code is manipulated in an entirely different way. People get excited about the topic of cloning. Like any controversial subject, there is a great deal of misinformation getting passed around. Start your research at the site listed below so we can make sure we all understand the basics.

The impact of human cloning has been popularized in fiction and played out with a variety of potential outcomes – but what are the realities? Spend some time browsing these two sites before completing the assignment.

THE TASK:

  1. Provide one (1) example of what happens when the genetic code hiccups. Share the link so others can see the example. Here’s a hint – think of inherited diseases, etc. (15 points)
  2. Your post should be a minimum of 100+ words – please cite any resources used. (5 points)
  3. State your stance on the issue and summarize the ethical controversy surrounding human cloning. (5 points)
  4. Leave substantive* comments on THREE (3) other student posts – select ones who wrote about different examples than you selected. Use this as an opportunity to learn what they have to share. (5 points each)
