Human Cloning—Angel or Satan?

Given that I am majored in biology, I will mainly speak about the subject of human cloning today.

4 billion years ago, life arose on the earth. Four billion years later, human beings begin to appear into the secrets hidden in the genes, which are the most delicate structure of life. A little more than a year ago, scientists completed the Human Genome Project, which is one of the three most significant advances in scientific history.

Cloning is the main strategy developed in the study of genes. To clone suggests to make genetically identical copies. As for human cloning, it is achieved by placing the genetic material from a donor??s somatic cell into a woman??s egg, which has already had its nucleus removed. That??s to say, the cloning cells share the same genetic supplies with the donor.

Essentially, Scientists have lengthy been studying animal cloning, even earlier than the birth of the sheep Dolly. But when it comes to human cloning, persons commence to diverse in their opinions. Some think human cloning as the angel although the other people regard it as the Satan.

The proponents for human cloning are right. Human cloning offers hope to the couples who can not have their personal children. Prior to the invention of human cloning, they have either to get eggs or sperms from donors or adopt a youngster, but with human cloning, they could use their somatic cells to build a kid of their personal.

Human cloning also offers rise to the production of stem cells. Stem cells have the capability to develop into all kinds of cells, for example, neuron cells, kidney cells or liver cells, thus stem cells can be utilized to culture human tissues and organs. Therefore, stem cells are necessary materials for each medicine and biology. Stem cells are derived from embryos made by human cloning.

Nevertheless, the opponents of human cloning are also proper. As a student of biology, I know clearly that a single results of animal cloning is built on thousands of failures. Most of the embryos die at an early age and many of the survivals are born with serious physiological defects. Most essential of all, life is a creation, not a commodity. Children are gifts to be loved and protected, not merchandise to be made or manufactured, not to be engineered to custom specifications.

Then, human cloning with the target to yield stem cells is not acceptable to most folks, mainly because it demands the…
