Redaction of Genetic Engineering

Introduction

First of all, I would like to give a brief comment about Genetic Engineering, which is a big step toward curing many diseases, althoug it can present ethical dilemmas.

Arguments for

As I have said before one of the main advantages is that, Genetic Engineering can cure many diseases that years ago were impossible to cure, for example, there has been a case in which a mother got pregnant using the DNA sequence of her son, who had a terrible illness, in order to use the organs of the new born baby, to cure the terrible disease of the son.

Arguments against

On the other hand, it raises many controversial dilemmas. Many people consider scientists and doctor aren´t gods. They can´t create life without thinking about the consequences of their acts.

Conclusion

In conclusion, although Genetic Engineerig can cure illnesses, the human beings aren´t still prepared to be gods.

INTRODUCTION

Should human people be cloned? Is it possible to clone a human? Is there moral and ethics? These are some questions that many people ask about this controversial issue. We have the technology to do it. We have the materials, but do we have ethical permission to do it?

ADVANTAGES

For some people cloning is good, because of the benefits we can get, and for example we can save some animals who are in extinction. And if we have a very dangerous ill and we need a transplant with this advance in science we can do it with out problems of organ rejection.

DISADVANTAGES

Many cloned animals like monkeys, cows, mice and some others had been born with abnormalities; strange sicknesses... and if we clone a human person, he or she may have somes abnormalities. Many countries have established laws in general terms for cloning animals, and especial laws to prohibit human cloning.

CONCLUSION

I think people should use cloning with a good reason and they have to respect the laws and the morals and ethics

Essay on human cloning

Introduction (what is cloning?)

Cloning an individual means obtaining an identical cell from a cell or a nucleus of another individual. For a few years they have been obtaining cloned mammals, but only from embryonic very early cells, due to the fact that they still have not entered differentiation.

Arguments for

The scientists hope that the mother cells you use to create human people could open the way for new treatments for diseases that otherwise would be incurable, such as Parkinson's disease, cardiac diseases, Alzheimer's disease, paralysis, cerebral spillages and the diabetes.

Arguments against

The high rates of failures and the high morbidity of the cloned animals indicate that it’s not applicable to the human. Besides, the cloned animals present, apparently, high rates of disability and deformity.

Conclusion

I think that cloning human people should be used only in case the embryo had some disease, deformity or disability

Human cloning

Introduction

Human cloning is generally used to refer to artificial human cloning. The most successful cloning was Dolly the sheep. Human clones have the form of identical twins. They are genetically identical, which doesn't mean altogether identical.

Arguments for

Therapeutic cloning could provide needed organ transplants. It can be used like a cure for cancer as well as a better treatment for heart attacks. It can be used with parents who are both infertile to have children, but I am not sure. Organ transplants can save lives. Cloning allows gay couples to have babies. It will be funny to see a person like you and that'll be very strange too.

Arguments against

I think it will be very dangerous. There will be health problems. Cloned human could die young. Reproductive cloning is expensive and highly inefficient. I think genes were more or less active compared to normal embryos. Problems may result from programming errors. Defects can appear in the genetic material due to abnormalities of cloned embryos.

Conclusion

I think humans shouldn’t be cloned. Several cloned animals have died prematurely from infections and other complications and humans can suffer the same problems.

My school trip to Granada

Luna St, 14

13th December 2006

Dear Ana,

I'm in Granada on a school trip. I'm with my class and our science teacher, Mr Martínez. We're doing a project on science.

At the moment, we're at the Science Park.

This evening we're going to the Museum. Tomorrow, we're having lunch at a café and we're going to the Alhambra.

Best wishes

Adela
