All About Cloning

(Complete Item Description)

Abstract:: "Normally, an animal gets half its DNA from its mother and half from its father. But Dolly had three mothers: one mother gave Dolly her DNA; one supplied an egg; and the third, her surrogate mother, gave birth to her. Dolly is an identical twin of the mother who gave her her DNA. But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.

American Stem Cell Research: Politics and Policies

(Complete Item Description)

Abstract:: This module reviews American stem cells policies from 1997 to the present. It covers both pre- and post-Dolly regulation and the impact of President G.W. Bush's stem cell policy.

"The Fountain of Life: From Dolly to Customized Embryonic Stem Cells, Fall 2007"

(Complete Item Description)

Abstract:: " During development, the genetic content of each cell remains, with a few exceptions, identical to that of the zygote. Most differentiated cells therefore retain all of the genetic information necessary to generate an entire organism. It was through pioneering technology of somatic cell nuclear transfer (SCNT) that this concept was experimentally proven. Only 10 years ago the sheep Dolly was the first mammal to be cloned from an adult organism, demonstrating that the differentiated state of a mammalian cell can be fully reversible to a pluripotent embryonic state. A key conclusion from these experiments was that the difference between pluripotent cells such as embryonic stem (ES) cells and unipotent differentiated cells is solely a consequence of reversible changes. These changes, which have proved to involve reversible alterations to both DNA and to proteins that bind DNA, are known as epigenetic, to distinguish them from genetic alterations to DNA sequence. In this course we will explore such epigenetic changes and study different approaches that can return a differentiated cell to an embryonic state in a process referred to as epigenetic reprogramming, which will ultimately allow generation of patient-specific stem cells and application to regenerative therapy. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching."

Stem Cells: A Cure or Disease?, Spring 2011

(Complete Item Description)

Abstract:: Have you ever considered going to a pharmacy to order some new cardiomyocytes (heart muscle cells) for your ailing heart? It might sound crazy, but recent developments in stem cell science have made this concept not so futuristic. In this course, we will explore the underlying biology behind the idea of using stem cells to treat disease, specifically analyzing the mechanisms that enable a single genome to encode multiple cell states ranging from neurons to fibroblasts to T cells. Overall, we hope to provide a comprehensive overview of this exciting new field of research and its clinical relevance. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

What Do You Know About Genetics?

(Complete Item Description)

Abstract:: This OLogy activity tests kid's knowledge about DNA, genes, cloning, and more with an interactive quiz. The 10-question multiple-choice test covers a wide range of topics, from "What is junk DNA?" to "What is one thing that makes one identical twin different from his or her other twin?" After making their 10 selections, kids can check their answers with a page that shows them how they did on each question and offers explanations of the right answers.
