cloning?

Postby victor » Sat May 14, 2005 1:00 pm

What gene should I take to make an almost perfect clone?

What do you mean "What gene?"? In order to make a clone you would need the entire cariotype. In a human that is about 37000 according to "Human genome" project results

Yes, to make a clone you have to 'transplant' the whole nucleus, not only some genes.

yea - unless u are talking about recombinant DNA (genetic manipulation by inserting genes of interest into the model organism) =D
化学は、最高です

cloning ummmm

CLONING IS HARDLY AS REVOLUTIONARY AS
YOU MIGHT EXPECT -- OR AS UNNATURAL
AS ITS OPPONENTS ARGUE. BUT THE SCIENCE
THAT MAKES IT POSSIBLE COULD ALSO
ALLOW THE RICH TO TURN THEMSELVES
INTO A DIFFERENT SPECIES.

lGenes are strings of chemicals that help create the proteins that make up your body. Genes are found in long coiled chains called chromosomes. They are located in the nuclei of the cells in your body:
II. "THREE WAYS TO MAKE AN EMBRYO"
In sexual reproduction a child gets half its genes from its mother (in her egg) and half from its father (in his sperm):Cloning is an asexual form of reproduction. All the child's genes would come from a body cell of a single individual: Who is the clonal child's genetic mother or father? As we understand those terms, a clonal child wouldn't have a genetic mother or father, it would have a single 'nuclear donor.' If a man cloned himself, would the child be that man's son or his twin brother? It would be neither, it would be a new category of biological relationship: his clone.
III. STEM CELLS
Stem cells are primordial cells capable of developing into a variety of types of cells. Some stem cells are found in the adult body. Others are found in very early embryos. These stem cells can be cultured in petri dishes and potentially used to generate "therapeutic tissues" or "spare organs":Many people support the use of stem cells of both types for such therapeutic purposes. Many others support the use of adult stem cells for this purpose but oppose the use of embryonic stem cells, because they oppose the destruction or manipulation of human embryos.

IV. HUMAN CLONING: A CRITICAL DISTINCTION BETWEEN TWO APPLICATIONS
1. Reproductive cloning uses the cloning procedure to produce a clonal embryo which is implanted in a woman's womb with intent to create a fully formed living child--a clone-as shown in diagram 3 above..

2. Therapeutic cloning uses the cloning procedure to produce a clonal embryo, but instead of being implanted in a womb and brought to term it is used to generate stem cells, as shown in diagram 4 above.

The purpose of using clonal embryos to generate stem cells is to allow creation of tissues or organs that the clonal donor can use without having these tissues or organs rejected by their body's immune system.

Most people oppose reproductive cloning. Some people oppose reproductive cloning but support therapeutic cloning. Others oppose therapeutic cloning as well as reproductive cloning, either because they are opposed to the destruction of embryos as a matter of principle, or because they feel the acceptance of therapeutic cloning will set us on a slippery slope to the acceptance of reproductive cloning and human genetic manipulation.

It is possible to support stem cell research and still oppose research involving therapeutic cloning.

V. HUMAN GENETIC ENGINEERING
Human genetic engineering means changing the genes in a living human cell. Suppose you had a lung disease caused by defective genes in your lung cells. If there was a way to fix those genes, you might be cured.

Scientists change the genes in living cells by putting the desired "new" gene into a little virus-like organism which is allowed to get into your cells and which inserts the new gene into the cell along with the "old" genes:


I hope I helped you let me know if I did in anyways plzz. byeeee Good luck !!!
I would like to become a pediactirc doctor. I also want to get into med-school. I attend UCLA.
