She was made through the process called transgenesis and this process was chosen because it worked in mice in the early 1980's and resulted in the successful cloning of rodents. The main reason that Dolly is so infamous in the cloning world is because she lived a long life and was able to successfully reproduce. They produced a total of six offspring. And this was a breakthrough because scientist did not know if clones could reproduce and Dolly was the answer. Dolly in the end was euthanized because she had arthritis and tumors growing in her chest. ]]> 2016-09-09 20:10:31 UTC https://padlet.com/greenenglish/7Bcloning/wish/122879770 https://padlet.com/greenenglish/7Bcloning/wish/122881655 When cloning a living animal or human, we use the DNA of that organism. Scientists are currently adding the DNA formula to a unfertilized embryo with the nucleus removed causing it to seem as a clone of the original DNA donor. Clones would live a shorter life span and be more vulnerable to diseases, because "human gene grows older with age... [so] the cloned individual would retain the age of the donor’s genes"(Wickman). If a man or woman 40 years old wanted to clone themselves, their 40 year old DNA and cells would be put into a newborn baby, and the baby would carry many of the bad genes that the man or women was beginning to develop. This would also cause premature aging which could lead to more side effects.]]> 2016-09-09 20:22:12 UTC https://padlet.com/greenenglish/7Bcloning/wish/122881655 https://padlet.com/greenenglish/7Bcloning/wish/122882065 Human cloning was used to create embryonic stem cells and from that new completely identical tissue to a patients can be grown. Many patients can benefit from tissue transplants like people diabetes and many other patients with diseases. https://www.theguardian.com/science/2013/may/18/human-cloning-heart-disease-genes]]> 2016-09-09 20:24:53 UTC https://padlet.com/greenenglish/7Bcloning/wish/122882065 https://padlet.com/greenenglish/7Bcloning/wish/122882246 Cloning is when different processes are used to make identical copies of organisms and cells. There happens to be three types of cloning which are gene cloning, reproductive cloning and therapeutic cloning.]]> 2016-09-09 20:26:22 UTC https://padlet.com/greenenglish/7Bcloning/wish/122882246 ceceshimizu https://padlet.com/greenenglish/7Bcloning/wish/122883354 The process of cloning has been around for years and it all started in the the early 1880's with sea urchins. The process began there and since has expanded to humans and larger mammals. Another important aspect to know is that endangered species are being cloned and it is assisting with bringing the population numbers up. Also an important piece of information to know is that depending on the species the process is different. ]]> 2016-09-09 20:33:10 UTC https://padlet.com/greenenglish/7Bcloning/wish/122883354 https://padlet.com/greenenglish/7Bcloning/wish/122883653 With a clone you can avoid the 8% of serious abnormalities in child birth. https://www.theguardian.com/science/2013/may/18/human-cloning-heart-disease-genes]]> 2016-09-09 20:35:19 UTC https://padlet.com/greenenglish/7Bcloning/wish/122883653 https://padlet.com/greenenglish/7Bcloning/wish/123316405 It can cost about 30,000 dollars to clone only a cat in the US. Scientist have also cloned cows for 20,000 dollars and horses for 150,000 dollars each. Although the cost of cloning is very high, the likelihood of success is only about 10% depending on the type of animal. ]]> 2016-09-13 00:35:41 UTC https://padlet.com/greenenglish/7Bcloning/wish/123316405 ceceshimizu https://padlet.com/greenenglish/7Bcloning/wish/123331592 The process of cloning is quite extensive and has taken years to create one cloned animal. The actual process can be explained somewhat simply.
Step 1) A biopsy is ttaken from the donor and inserted into an egg cell from another animal from the same species. The nucleus has been removed so that the donors DNA is duplicated.
Step 2) This new embryo is hit with electricity so that the cells start multiplying and becomes a small clump of cells.
Step 3) This clump of cells is implanted into the surrogate mother. The newborn that is born will be a genetic replica of the donor specimen. http://www.livescience.com/32295-how-does-cloning-work.htm]]> 2016-09-13 03:13:08 UTC https://padlet.com/greenenglish/7Bcloning/wish/123331592
