organism that is the exact genetic copy of another. There are multiple ways that cloning can be achieved through biotechnology. Artificial embryo twinning is the more basic version of cloning. It mimics the natural occurrence of twins as a zygote divides into a two celled embryo but this process takes place in a Petri-dish instead of the mother’s body. The resulting embryos are then placed in a surrogate mother where they are developed. The process that ‘cloning’ generally refers to is scientifically known

A single sperm fertilizes the egg; the others are locked out. ’ (Time‚ 1997‚ pg. 66) Once the egg has been fertilized‚ cell division begins and the embryo drifts down the Fallopian tube. The embryo reaches the uterus in about a week. The embryo anchors itself to the wall of the uterus where it develops into a foetus. The foetus feeds off nutrients and oxygen provided by the placental lining in the uterus. There are several conditions in both

However‚ new biomedical technologies which have been introduced in the critical area of human life and the family have given rise to further questions‚ in particular in the field of research on human embryos‚ the use of stem cells for therapeutic purposes‚ as well as in other areas of experimental medicine. These new questions require answers. The pace of scientific developments in this area and the publicity they have received have raised expectations

stem cell research funding was cut off by President Bush. He explained his actions by stating‚ "If this bill would have become law‚ American taxpayers would‚ for the first time in our history‚ be compelled to fund the deliberate destruction of human embryos. And I’m not going to allow it"(Stem Cells Timeline) Ever since the discovery of cells that can replicate a specialized cell and self-renew by mitosis‚ also called stem cells‚ scientists have been wondering where the research might go. Now that the

cells can be extracted from both adults and young embryos. The differences of an embryonic stem cell and an adult stem cell in most peoples eyes are that cells can be extracted from adults for research without harm to adult‚ but those extracted from embryos are the result of the destruction of the embryo. Scientists believe that although adult stem cells can be helpful in the research in disease‚ those cells are inferior to those of a human embryo because the embryonic stem cell can developing in

Gametophytes of gymnosperms are microscopic and completely dependent on the large‚ free living sporophyte. One advantage of this is that the delicate female gametophytes do not have to cope with environmental stressors - female gametophytes and the embryos they produce are sheltered from drought and harmful UV radiation by their enclosure within the moist reproductive tissues of the parental sporophyte generation. Nutrient exchange also occurs between gametophytes and their parents. In contrast‚ the

Embryonic Stem Cell Research Should Be Federally Funded The undifferentiated cells of a human embryo‚ referred to as stem cells‚ hold limitless promise for medical research. When a human embryo consists of not more than 64 cells‚ its cells are able to learn new ways of being. If injected into a diseased kidney‚ they take on many of the properties of ordinary kidney cells‚ and may help the kidney to perform its normal function. This seems to hold for any organ‚ even any kind of cell. (Goldstein)

The Ministry of Health’s role is basically to lay the policy and the direction of health services in the country and to show the commitment of the Government‚ and the powers-to-be‚ that health is of utmost importance in nation building. And the role of the ministry is to enforce regulations and be the regulator. Imagine if there is no Ministry of Health‚ anybody can make the claim that their product is the best for health; anybody can set up a hospital. Nobody to regulate the quality of the workforce

With Dolly the sheep‚ scientists used the technique of “embryo splitting” and created a perfect clone of a sheep. Since Dolly the sheep was created there have be regulations preventing anymore research which might lead to a clone being produced. With stem cell research many advances in medical field occur every
