Reproductive Cloning and Animals
Transcript of Reproductive Cloning and Animals
What is Reproductive Cloning?
the production of an organism with the same genetics
genetics carry info about physical and behavioral characteristics from their parents
genetic instructions are transported from living cells throughout the body in a molecule called DNA(Deoxyribonucleric Acid)
organisms that have the same genetic makeup are clones
reproductive/organism cloning is a production of an organism with the same genetics as the organism
scientists use the word cloning as a duplication of cells and genes in a laboratory
people think that cloning is a laboratory technique of making living copies of animals or other organisms
2 Ways Cloning can be Achieved
in 1950, scientists used nuclear transfer to clone amphibians
in 1996, a British scientist named Ian Wilmut used this procedure to clone a sheep named Dolly
further success in cloning technology may yield important benfits for many people
the cloning of the many animals may enable scientists to create livestock with the gentic traits from the animals
livestock may produce higher quality meat, milk, and wool
The Story Of Dolly
Ethical Issues in Animal Cloning
difficult to produce healthy clones
most cloned embryos don't survive to reach birth
cloned animals have higher incidence of birth defects
some cloned animals suffer developmental problems and die soon after birth
cloning human embryos are used for stem cells
human embryos are destroyed while making stem cells
high incidence of abnormalities in cloned animals
Why Humans are Interested in Cloning Animals
used to make stem cells for research
use genetically engineered animals to produce drugs and proteins for medicine
used to attempt to revive endangered or extinct species
used to reproduce a deceased pet, however will not be the exact same as the original

Other Animals that have been Cloned
Dolly - sheep, first mammal to be cloned from an adult animal body
suffered from health issues combined with premature aging
gave birth to Bonnie
passed away at the age of 6
