They have the remarkable potential to develop into many different cell types in the body during early life and growth.
Introducing genes into an affilicted individual for therapeutic purpose
Q. what is totipotent?
A totipotent cell has the capacity to form an entire organism.
the facts
1. A clone is an exact copy of an organism, organ, single cell, organelle or macromolecule.
2. Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA.
3. This primer on stem cells is intended for anyone who wishes to learn more about the biological properties of stem cells, the important questions about stem cells that are the focus of scientific research, and the potential use of stem cells in research and in treating disease.
4. Gene therapy is an experimental technique that uses genes to treat or prevent disease.
5. Gel Electrophoresis is the process in which molecules (such as proteins, DNA, or RNA fragments) can be separated according to size and electrical charge by applying an electric current to them.
gene cloning is useful for two basic purposes: to make many copies of a particular gene and to produce a protein product. In this simplified diagram of gene cloning, people start with a plasmid isloated from a bacterial cell and a gene of interest from another organism. only one copy of the plasmid and one copy of the gene of interest are shown at the top of the figure, but the starting materials would include many copies of each.http://www.youtube.com/watch?v=rrT5BT_7HdI
Biotechnology, or the genetic modification of living materials, has ignited heated debates over trade policy. Innovations in the manipulation of microbes, plants, and animals raises serious ethical questions related to the commoditization and exchange of living organisms. Agricultural concerns center on issues of 'genetic pollution' or the genetic flow from GM crops to unmodified plants in the wild. Transfer of genes from GM to wild plants could create health problems in humans, anti-biotic resistance in plants and associated insects, long-term damage to ecosystems, loss of biodiversity, and lack of consumer choice. Biotechnology issues related to intellectual property rights are concerned with the moral and ethical implication of patenting living organisms. Biotechnology and its products have created some amazing possibility as well as raised fears among many of their potential negative consequences. There is also the moral dimension of playing with living beings. Nevertheless, the technology and its products are here to stay.
