Which Of The Following Is True Of The Cloning Experiment That Resulted In Dolly The Sheep?

How was Dolly the sheep cloned?

Dolly the sheep was successfully cloned in 1996 by fusing the nucleus from a mammary-gland cell of a Finn Dorset ewe into an enucleated egg cell taken from a Scottish Blackface ewe. Carried to term in the womb of another Scottish Blackface ewe, Dolly was a genetic copy of the Finn Dorset ewe.

What did the cloning of Dolly demonstrate?

Dolly was remarkable in being the first mammal to be cloned from an adult cell. This was a major scientific achievement as it demonstrated that the DNA from adult cells, despite having specialised as one particular type of cell, can be used to create an entire organism.

How was Dolly the sheep produced through cloning quizlet?

How was dolly the sheep produced? was produced by the process of nuclear transfer. this involved scientists placing the nucleus of a body cell(an udder cell) from the sheep they wanted to clone into an empty egg cell which had had its nucleus removed. it was then implanted into another sheep to grow.

Which of the following is incorrect about Dolly the clone?

The correct answer is The cloned sheep dolly did not resemble either of the parents. Cloning is the process of developing exact copies or clones of a particular gene or DNA sequence using the principles of genetic engineering.

Is cloning illegal?

Under the AHR Act, it is illegal to knowingly create a human clone, regardless of the purpose, including therapeutic and reproductive cloning. In some countries, laws separate these two types of medical cloning.

Is human cloning possible now?

There currently is no solid scientific evidence that anyone has cloned human embryos. In 1998, scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells.

How much did it cost to clone Dolly the sheep?

At $50,000 a pet, there are unlikely to be huge numbers of cloned cats in the near future. In Britain, the idea is far from the minds of most scientists. “It’s a rather fatuous use of the technology,” said Dr Harry Griffin, director of the Roslin Institute in Edinburgh, which produced Dolly.

What are the two types of cloning?

There are three different types of cloning:

  • Gene cloning, which creates copies of genes or segments of DNA.
  • Reproductive cloning, which creates copies of whole animals.
  • Therapeutic cloning, which creates embryonic stem cells.

What are the 6 steps to cloning?

In standard molecular cloning experiments, the cloning of any DNA fragment essentially involves seven steps: (1) Choice of host organism and cloning vector, (2) Preparation of vector DNA, (3) Preparation of DNA to be cloned, (4) Creation of recombinant DNA, (5) Introduction of recombinant DNA into host organism, (6)

Why is the cloning of Dolly the sheep important to humans?

Why was Dolly so important? Dolly was important because she was the first mammal to be cloned from an adult cell. Her birth proved that specialised cells could be used to create an exact copy of the animal they came from.

Why is the cloning of Dolly the sheep important to humans quizlet?

Terms in this set (28) Why is the cloning of Dolly the sheep important to humans? – Cloned animals can produce more offspring. Animals that produce human medicines could be cloned.

How might cloning eventually help humans live longer?

Cloned human organs could be used to replace unhealthy ones b. Clones tend to live longer than the organisms they take their DNA from c. The food obtained from cloned animals and plants would be healthier and more life-sustaining than ordinary food 6. Tim says that genetic diversity helps species survive.

How did Dolly the sheep die?

Death. On 14 February 2003, Dolly was euthanised because she had a progressive lung disease and severe arthritis. A post-mortem examination showed she had a form of lung cancer called ovine pulmonary adenocarcinoma, also known as Jaagsiekte, which is a fairly common disease of sheep and is caused by the retrovirus JSRV

What are the ethical issues with cloning?

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.

How does cloning benefit the environment?

Animal cloning offers great benefits to consumers, farmers, and endangered species: Cloning allows farmers and ranchers to accelerate the reproduction of their most productive livestock in order to better produce safe and healthy food. Cloning can be used to protect endangered species.
