What is wrong with genetic cloning?

Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.

Is genetic cloning possible?

The news that researchers have used cloning to make human embryos for the purpose of producing stem cells may have some people wondering if it would ever be possible to clone a person. Although it would be unethical, experts say it is likely biologically possible to clone a human being.

Is it possible to make a clone of a gene?

A gene is a specific section of DNA. Scientists can clone genes by transferring them from one organism to another and getting them to replicate. This is called DNA cloning or recombinant DNA technology. Making a clone of a human embryo is the most controversial type of cloning.

How is cloning used to eradicate diseases?

Using Cloning to Eradicate Disease A gene is a specific section of DNA. Scientists can clone genes by transferring them from one organism to another and getting them to replicate. This is called DNA cloning or recombinant DNA technology.

How are inherited diseases passed on to the next generation?

Some inherited diseases, for example cystic fibrosis, are called autosomal recessive disorders, and require both genes in the genetic pair to be abnormal for the disease to develop. A person who carries only one abnormal gene for a recessive disorder will not develop the disease, but can pass it on to the next generation.

When does a disorder occur in only one copy of the gene?

When a disorder is dominant, the disease can occur when there are DNA mistakes in only one of the two gene copies. This means that if a parent has the DNA change, there is a 50-50 chance that it will be passed on to each child. When a disorder is recessive, there must be mistakes in both copies of the gene for the disorder to occur.
