Cloning

Cloning in biology is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms.

What is cloning?

Is scientific procedure that consists of taking the genetic material from one organism to get another identical called clone. Through cloning there is not egg with sperm binding.

How come cloning experiments?

The progress of knowledge and subsequent technical advances in the area of molecular biology, genetics and artificial fertilization has made possible, for some time, experimentation and making cloning of plants and animals.

Chronology of cloning

1996: Cloning of the first mammal, a sheep named "Dolly."

1997: An investigator cloned 22 mice alive

2000: In Scotland formed a controversy with the first cloning of pigs

2001: The scientific Westunsi Marck, created Copycat a cloned cat.

Since 2006 we have seen cloning af: a cow, a dog, a camel and a bull.

Today a Russian university is trying to clone a mammoth, an extinct species 4500 years ago

Advantages of cloning:

1. Improvement of the species.

2. Currently there are many plant and animal species to extinction, cloning would permit to preserve for the future.

3. In the specific case of human cloning, the capacity to restitute function in organs with damage

¿Qué es la clonación?

Es el procedimiento científico que consiste en tomar el material genético de un organismo para obtener otro idéntico, denominado clon. A través de la clonación, no hay una unión de óvulos con espermatozoides.

¿Como surgen los experimentos y sus impactos correspondientes en la sociedad?

Los progresos del conocimiento y los consiguientes avances de la técnica en el campo de la biología molecular, la genética y la fecundación artificial han hecho posibles, desde hace tiempo, la experimentación y la realización de clonaciones en el ámbito vegetal y animal.
