Reaction Paper to Beyond the Genome Science and Society - Fall 2007 Presented by Dave Cloud Summary of Beyond the Genome The articles “Beyond the Genome”, and “DNA Dilemmas” explores the positive and negative characteristics of genetic research in the 1990’s and beyond. The authors use ethical principles, case studies, and opinion poles from various age groups to assemble public reaction to what is emerging as a very complex issue in our society today. They ponder the questions of intervention

Genetic profiling at birth: a storm in a teacup? 18 August 2003 By Juliet Tizzard Director, Progress Educational Trust Appeared in BioNews 221 This week's BioNews reports on an interview with Human Genetics Commission chair, Baroness Helena Kennedy, in which she describes the idea of carrying out genetic profiling of newborn babies as 'unlikely'. In the interview, published in the Financial Times, Kennedy voices her concern that we might rush ahead with new genetic tests before the public is

mother, but is nearly independent of the age of the father. • Each time a cell divides, the genetic material becomes shorter. • The ends of the chromosomes, known as "telomeres", are important for the genetic stability of the cell and they act as a DNA clock that measures the age of the cell. • The cell stops dividing and dies when the telomeres become too short. • The discovery that the egg cell can extend the telomeres of a fertilizing sperm cell is important in the development of stem cell therapy

Genetic Engineering Although genetic engineering is an entirely new field, it has fascinated mankind for many years. Genetic engineering gives the power to change many aspects of nature and could result in a lot of life-saving and preventative treatments. Today, scientists have a greater understanding of genetics and its role in living organisms. However, if this power is misused, the damage could be very great. Therefore, although genetic engineering is a field that should be explored, it needs

to make copies of itself—its DNA—in a structure called a chromosome. In addition, it may have extra loose bits of DNA called plasmids floating in the cytoplasm. Bacteria also have ribosomes, tools necessary for copying DNA so bacteria can reproduce. Some have threadlike structures called flagella that they use to move. o A virus may or may not have an outermost spiky layer called the envelope. All viruses have a protein coat and a core of genetic material, either DNA or RNA. o The main difference

change. Without genetic diversity, everything would look the same generation after generation. Ultimately, over time the species would become extinct. Mutation is changing the structure of a gene resulting in a different form in future generations. DNA is constantly subject to mutation or changes in the code. Mutations can be a good or bad thing. Most are actually good for us. “The good mutations that keep the world healthy are called silent mutations.” (www.geneticstheteach.org) But the mutations

The first weeks of the summer fellowship in the VDS stream was a bit hectic. They consisted of learning protocols and techniques. Three plates of PNiC-BSa4 colonies were grown by my partner and me that week. These were later used by the majority of lab students who had reached the cloning stage. My first PCR with plasmid pgbr22 failed, but the second was successful. PCR with pmCherry had to be completed 3 times to get a successful result and PNIC-BSa4 PCR had to be completed twice to get a successful

of cloning are : (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning. I learned a lot from this article something that I found was really interesting is this process called "somatic cell nuclear transfer". This process is where the scientist transfer genetic material from the nucleus of a donor adult cell to an egg whose nucleus, and then its genetic material, has been removed. The reconstructed egg containing the DNA from a donor cell must be treated
