what is animal and human cloning?
155172
Cloning creates a genetically identical copy of an animal or plant. Many animals - including frogs, mice, sheep, and cows - had been cloned before Dolly. Plants are often cloned - when you take a cutting, you are producing a clone. Human identical twins are also clones.

Dolly the Sheep. Dolly (July 5, 1996 - February 14, 2003), a ewe, was the first mammal to have been successfully cloned from an adult cell. She was cloned at the Roslin Institute in Midlothian, Scotland, and lived there until her death when she was six years old. Her birth was announced on February 22, 1997.

Ethical issues specific to human cloning include: the safety and efficacy of the procedure, cloning for destructive embryonic stem cell research, the effects of reproductive cloning on the child/parent relationship, and the commodification of human life as a research product.

Transgenic animals are animals (most commonly mice) that have had a foreign gene deliberately inserted into their genome. Such animals are most commonly created by the microinjection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a pseudopregnant surrogate mother.

Most non-mammalian animals have nuclei in their mature erythrocytes, or red blood, cells, but mammals, including humans, do not. Comparing mammals, the main difference between the blood of two different species is the same as the difference between two people; the proteins that allow for self-identification.

A. A knockout animal has definite inactivated piece of DNA, whereas a transgenic animal usually has an unknown activated piece of DNA.

Therapeutic cloning creates a line of embryonic stem cells genetically identical to an individual. Reproductive cloning creates a new organism genetically identical to an individual.

All humans are Homo sapiens and all Homo sapiens are human. We are a species, not a breed or race. ... All the breeds of an animal are of the same species. Breeds are just groups of individuals inside a species sharing a group of characteristics (size, color, hair, etc).

A human is a member of the species Homo sapiens, which means 'wise man' in Latin. Carolus Linnaeus put humans in the mammalian order of primates. Humans are a type of hominid, and chimpanzees, gorillas and orangutans are their closest living relatives. Humans are mammals. They are also social animals.

Animal Research Saves Animals, Too Practically all biomedical research with lab animals advances veterinary medicine as well as human medicine and helps pets and wildlife live longer, happier, and healthier lives. Dozens of diseases, from cancer to epilepsy, affect both animals and humans.

Swine are considered to be one of the major animal species used in translational research, surgical models, and procedural training and are increasingly being used as an alternative to the dog or monkey as the choice of nonrodent species in preclinical toxicologic testing of pharmaceuticals.

Definition. Animal cell refers to a eukaryotic cell that lacks a cell wall and a large nucleus whereas human cell refers to the basic functional unit of the human body. The human cell is a type of animal cell.

Cloning or clone reproduction is an in vitro process of obtaining multiple copies of the same organism using molecular biological and genetic engineering techniques. Asexual reproduction is the process where new organisms are produced without the fusion of gametes or reproductive cells (sperms and ova).

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.

The genetic material of apes is identical to that of humans to a very large degree. Differences are especially small in the nuclear DNA. Certain genes that were analyzed differ by only 1.2% between humans and chimpanzees, by 1.6% between humans and gorillas and by 1.8% between gorillas and chimpanzees.

It was 20 years ago this week that scientists announced the first successful cloning of a mammal — the now-famous sheep Dolly — from a cell taken from an adult animal. ... Prior to Dolly, scientists had been able to clone mammals only by splitting growing embryos.

New surgical techniques are developed and practiced in pigs because their organs are a similar size to those of humans. ... The pig organs are so similar to human organs, it is the best candidate as an organ donor for animal to human transplants.
