DNA: deoxyribonucleic acid is the information "blue-print" of the cell. It is a nucleic acid and is made from building blocks called nucleotides. This genetic information is passed from parent to child... more
Egg: a female gamete, which keeps all the parts of a cell after fusing with a sperm.
Ethics: a part of philosophy where the idea of right and wrong are discussed and recommendations of correct conduct are made. In other words what is the best way society should behave and people to live.
Gamete: specialized cells found in your reproductive organs that have half the amount of DNA of somatic cells. These cells combine to make a fertilized egg... more
Gene: a region of DNA that instructs the cell on how to build protein(s). As a human, you usually get a set of instructions from your mom and another set from your dad... more
Nucleus: where DNA stays in the cell, plural is nuclei.
Somatic cells: the cells in your body, except for gametes. Soma is Latin for body.
Sperm: a male gamete, which only transfers its DNA to the egg... more
There are several issues that are brought up by cloning. The logical conclusion to most research done with cloning is the question of cloning people. Cloning of people is currently illegal in the United States and many other countries. There are two main applications of cloning that bring up serious legal and ethical questions.
The first main application of cloning is that the technology can be used to create "designer children." The ability to choose specific genetic material you want to and make a child means that people could custom make their children. This worries people because of the possible use of the technology to make children to save another person from an illness, or to make another person to harvest organs from, or to take the genetic material of a great athlete. The question is: does the designed child have a right to lead life without the burden of the original purpose they were created for?
The second main application of cloning is that the technology can be used to create "stem cells." Stem cells are cells that have not decided what they are to become. Stem cells can theoretically become anything. This makes stem cells important in disease treatment. Stem cells are extracted from an embryo. A fertilized egg will create an embryo. An egg that has had its nucleus removed and replaced by a somatic cell will create an embryo. This act of removing stem cells, stops the embryo from living. Using the nuclear transfer method will create a designer embryo. This designer embryo will have the same cell type as the donor nucleus. The question is: will people start making designer embryos to create stem cells that might save them from disease years from now?
Of course, there are many other issues within issues here. You might know of several. The way to answer these ethical and legal issues is through discussion, education, and scientific research. That means you need to talk with people, listen at school, and maybe even become a scientist yourself!
