In 2003, scientists accomplished a feat straight out of science fiction: the cloning of the extinct Pyrenean ibex. However, the resulting clone died soon after its birth due to a lung defect. If a clone of an extinct animal that had died out only three years beforehand could not survive, is there any possibility of a real Jurassic Park? Because no dinosaurs are around to produce offspring, cloning is the only way to create a viable dinosaur embryo. Clones require a somatic cell nucleus and a fertilized egg cell sans nucleus.
The scientists take a cell from a model (could be an animal, plant, or a human) and remove its core, which contains the entire hereditary material and that contains 46 chromosomes. Then, they implant the core that was removed in an empty cell that had its core removed too, and finally, the egg is fertilized and is entirely complete with the 46 chromosomes that it would have had in a natural sexual fertilization process. The only difference is that the 46 chromosomes are from 1 person and not 2, as you are creating a copy of someone. So basically, if someone clones himself, the produced model is not his sister, brother, son, or daughter, but it’s just a new category of humans, which is that person’s clone/copy. Whilst many scientists now consider the process of human, plant, and animal cloning as a huge invention, still, everything has its pros and cons, and human cloning, of course, is not an exception.
Reproductive cloning is the production of a genetic duplicate of an existing organism. A human clone is therefore a genetic copy of an existing person. Reproductive cloning of humans was believed to be impossible until the birth of Dolly the sheep. Dolly was the first mammal to be cloned from an adult cell. Following this major scientific and technological breakthrough, it raised the possibility that humans can be cloned using the same procedure‒ somatic cell nuclear transfer (SCNT).
Most forms are from a random genetic mutation in either the father’s sperm or the mother’s egg rather than from either of the parent’s complete genetic makeup. Another cause of dwarfism is Turner Syndrome which is when a sex chromosome is missing or partially missing in girls or females and they inherit an X chromosome from each parent. Growth hormone deficiencies are also linked to genetic mutations that can result in dwarfism and some causes are just unknown. Dwarfism is typically defined as an adult height of 4 feet 10 inches or less and the average height among people with dwarfism is 4 feet. Dwarfism is usually divided into two categories; disproportionate dwarfism which is where some parts of the body are small and some parts are average or above average and this type prevents the bones from developing.
Scientists confirm that Seahorses, Snapdragons and Pipe Fish are the only vertebrates in which the males carry the burden of pregnancy. This type of phenomenon is one that leaves more unanswered questions than answers. This pregnancy doesn’t look the same in all species. In some cases, the seahorse brood pouch (the male alternative to a uterus) stores the fertilized eggs to attach while they develop. In other cases, after the mom deposits the eggs in the brood pouch, the eggs are fully enclosed and protected from the outside world.
Time We Played God On the 5th of July, 1995, Dolly the sheep was born. She was the first living organism to be cloned entirely from another. It was the first milestone in the history of human bio-engineering, but at the moment she was born, genetic research on humans was brought to a screeching halt. Since then, every single attempt at the cloning or engineering of the human genome has been blocked by the government, for reasons of ‘morality’ and ‘ethnical standards’. Many critics are calling out genetic engineering as humans ‘playing god’.
Is it morally right to terminate a pregnancy before normal childbirth? A fetus is a form of life, and every human being deserves the right to live, but when does a fetus become sufficiently human to have the right to life? The 'Catechism of the Catholic Church ' states that the embryo must be treated as a person from conception (6). However the embryo is still inside the pregnant woman, it is a part of her body and it feeds on whatever she eats. I believe that the fetus becomes a human being at the time of its birth, when it separates from the womb of its mother, and has to rely on its own resources to stay alive.
This research paper is about the Genetic disease called Progeria. The medical term for Progeria is Hutchinson-Gilford Progeria Syndrome or HGPS. Progeria is caused by a single nucleotide substitution. Progeria cannot be passed down from parent to child. Progeria is caused by random accident during cell division.
In the economically unpredictable country, the United States of America, there is obvious signs of corporate exploitation of the middle and lower classes in terms of economic status. However, the last thing you would think of are these huge food corporations scheming a class-based geographical empire of fast food chains with a scarcity of supermarkets. Food deserts are urban and rural areas, mainly of the lower class, that have virtually no access to healthy food options. Leading to more obesity and other dietary related diseases, such as diabetes. There are about 23 million people that live in food deserts, and out of that 23 million, “[more] than half of those people (13.5 million) are low- income” (Agricultural Marketing).
The second type of surrogacy is gestational surrogacy. Gestational surrogacy uses in-vitro fertilization by taking the egg of the biological mother and the sperm of the biological father and placing the embryo into the uterus of another individual. Surrogacy is performed for many reasons including: same-sex marriage, damaged uterus, age, history of miscarriages and other medical conditions. Although surrogacy is the safest option for most people, it raises many legal issues. Legal issues include the following: legal parents, refusal of custody from surrogate to biological parents and surrogacy contracts.
