How does reproductive cloning occur?
The Reproductive Cloning NetworkReproductive cloning involves removing all the DNA from a female egg, and the injection of DNA from an adult body cell (e.g. a skin cell). The cloning technique is called nuclear transfer, and is very similar to ICSI (intra cytoplasmic sperm injection) a procedure members of International Cloning Consortium have performed numerous times.

Related QuestionsWhat are therapeutic cloning and reproductive cloning?
HumGen - FAQCloning can be used for reproductive purposes (creating new organisms) or as a treatment option (using embryonic stem cells for therapy). The difference between these two techniques is their ultimate goal.
Related QuestionsWhat is the difference between cloning and other reproductive technologies already in use?
Animal Cloning>>Frequently Asked QuestionsCloning is in some ways an extension of assisted reproductive technologies already in use in agriculture, and in other ways it is a radical departure from how animals have traditionally been bred. Selective breeding, in which only those animals with desired traits are chosen for reproduction, has been used by farmers for centuries. More recently, selective breeding practices have intensified, aiming for ever greater production and lower costs, often sacrificing animal welfare in the process.

Frequently Asked Questions | The Harvard Stem Cell InstituteReproductive cloning involves creating an embryo by nuclear transfer and then implanting it into a uterus and allowing it to establish a pregnancy. This has been achieved for sheep and several other mammalian species. It is not known whether it could be made to work in humans, but the vast majority of researchers in the field are strongly opposed to attempting such an experiment.
Related QuestionsWhat is the difference between therapeutic cloning and reproductive cloning?
Australian Stem Cell CentreTherapeutic cloning is the process by which an embryo is created through nuclear transfer in order to obtain stem cells from it for therapeutic purposes. Reproductive cloning is the process by which an embryo is created by nuclear transfer and implanted into a surrogate mother in the hope of bringing it to term. Therapeutic cloning, or somatic cell nuclear transfer (SCNT) uses cloning technology to develop stem cells for research, and ultimately for therapy.

Frequently Asked Questions About Chronic Wasting DiseaseCWD is relatively rare. In Colorado, for example, fewer than 200 cases, mostly in mule deer, have been documented since 1981. In checking hunter-harvested animals, less than 6% of deer and 1% of elk in north-central and northeastern Colorado were found to have CWD. Similar surveillance in southeastern Wyoming also indicated that less than 7% of deer had CWD. Deer and elk checked outside these areas in Colorado and Wyoming did not have CWD.

Graduate School of Biomedical Sciences | Stem Cell Research ...Cloning is a procedure where the genetic material (DNA) of an individual is taken from an adult cell (for example, a skin cell) and then transferred into an oocyte (an egg). Before the adult cell DNA is placed into the egg, the scientist removes the egg's existing DNA. Thus, after the adult DNA is transferred into the egg, the new egg has the DNA of the skin cell. To put what would occur in perspective, if the skin cell is from Mr. Jones and the egg is from Ms.
Related QuestionsAnimal Cloning>>Frequently Asked QuestionsCloning is the term commonly used to refer to a procedure known as somatic cell nuclear transfer (SCNT), the procedure which was first used to create Dolly the sheep in 1996. In SCNT, the nucleus (which contains the genetic material of an animal) is removed from an unfertilized egg and replaced with the nucleus of an adult (somatic) cell from the donor animal to be cloned, ultimately resulting in an animal that is an almost exact genetic copy of the donor (though some differences remain).Related Questions
Genomics|Frequently Asked QuestionsThe term cloning that you might have heard or read about in the news usually refers only to one type called reproductive cloning. There are actually three types of cloning technologies and they include (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning.

How does cloning affect the DNA of animals?
BIO | Frequently Asked Questions, Animal CloningCloning does not change DNA, and clones are not genetically engineered animals. It is simply assisted reproduction, similar to embryo transfer, artificial insemination, or in vitro fertilization.

Related QuestionsWhere does BSE occur?
Bovine Spongiform Encephalopathy (BSE; Mad Cow Disease)BSE was first observed in Great Britain in April 1985 and was officially diagnosed in 1986. By June 1990, some 14,000 cases were confirmed (out of an estimated population of 10 million cattle) in Great Britain. Since 1986, more than 185,000 cases of BSE have been confirmed in Great Britain. The epidemic peaked in 1992-93 at almost 1,000 new cases per week. Control measures have since reduced incidence of the disease, and currently fewer than 100 new cases are reported per week.
Related QuestionsWhy does it occur?
Untitled DocumentFistula occurs when emergency obstetric care is not available to women who develop complications during childbirth. This is why women living in remote rural areas with little access to medical care are at risk. Before the medical advances of the 20th Century, fistula was quite common in Europe and the United States. Today, fistula is almost unheard of in high-income countries, or in countries where obstetric care is widely available.

Related QuestionsHow Does Hearing Loss Occur?
OTG, Inc. - Specializing in Onsite Pulmonary Testing, Mobile...Sound enters your ears in sound waves. These sound waves hit your eardrum and are converted to pressure changes in the inner ear. This causes special nerves to impulse, which are read by your brain as sound. When these nerves are exposed to a surplus of pressure changes, they may become damaged. You may have noticed that if you listen to loud music for several hours that your ears "ring." This is a Temporary Threshold Shift, or a temporary reduction in hearing.

Related QuestionsHow does natural conception occur?
In-Vitro Fertilization (IVF) - WikiFAQ - Answers to Frequent...Conception, or fertilization, occurs when the male's sperm meets with the woman's ovum (egg) and successfully penetrates it. This typically takes place in one of the woman's fallopian tubes and the fertilized egg then travels to the uterus and implants in the uterine lining. For pregnancy to take place, fertilization of the egg must be followed by a successful implantation. Only one egg is released for fertilization in each menstrual cycle.

Related QuestionsHow does vasa previa occur?
Frquently Asked QuestionsThe theory about this that makes most sense is called Trophotropism. The easiest way to explain this is to make a comparison to a plant. A plant will lean towards the sun to get the light it needs to survive. Since the lower segment of the uterus is not as nourishing as the upper segment, the placenta will grow to reach more nourishing tissue. The placental mass will erode away from the cervix, but the vessels can't. This also explains the velamentous insertion of the cord.
Related QuestionsWhy does organ rejection occur?
Organ Transplant, SVCMC; New York NYYour body has a natural defense system called the immune system that protects you from infection and disease. The immune system defends your body by producing "killer" cells that destroy foreign substances (such as viruses and bacteria). Since the donor organ doesn't match your old organ exactly, your body tries to destroy the transplanted organ. Essentially, a transplant creates a new disease called rejection. Rejection is nature's way of protecting your body.

Breast implant information, plastic and cosmetic surgeryThe post-operative infection rate of surgical placement of a saline implant is estimated at less than 1-2 percent. This rate is the same as the expected infection rate of any "clean" surgery as well and is documented in existing surgical literature. Infection after breast augmentation is unusual but can be a serious problem. Infections usually developed in only one breast. If it were to occur , it most commonly happens within the first 10-14 days after surgery.
