Cloning essay outline
The human genome consists of somewhat more than 3 billion nucleotides She was born on 5 July but not announced to the world until 22 February Once the technology of cloning is misdirected, the technology has the potential to develop terrifying effects This is known as reproductive cloning Naik. The eminent biologist E. Examples of dominant disorders are some forms of retinoblastoma and other kinds of blindness, achondroplastic dwarfism, and Marfan syndrome which is thought to have affected President Lincoln. He published the findings in a Chinese science journal. In this report I will tell you about genetics, cloning and whether I think it is wrong or right. Thus, every human has about 60 new mutations 30 in each genome that were not present in the parents. Some people consider cloning a major victory for technology and the economic outlook of the world. Think of all the possible benefits that make many scientists prepared to cross those ethical boundaries: Firstly, couples who have tried a long time for identical twins, triplets or even quintuplets! Megan and Morag  cloned from differentiated embryonic cells in June and Dolly the sheep from a somatic cell in Artificial cloning of organisms[ edit ] Artificial cloning of organisms may also be called reproductive cloning. However, never before has it sparked more interest then with the advent of Dolly, which represents the possibility that human lives could change in more than conceivable ways, upsetting the whole dynamics of procreation. Gene cloning is essentially recombinant DNA technology, where a piece of foreign DNA is inserted into a vector, which can be copied by a host cell
Genetic disorders may be dominant, recessive, multifactorial, or chromosomal. Germ-line genetic therapy would seek to correct a genetic defect, not only in the organs or tissues impacted, but also in the germ line, so that the person treated would not transmit the genetic impairment to the descendants.
The risk of endangering lives. There are three types of cloning: gene cloning, reproductive cloning and therapeutic cloning.
The eminent biologist E. In recessive disorders, the defective allele must be present in both alleles, that is, it is inherited from each parent to be expressed.
Therefore, the government should financially support the research of therapeutic cloning while condemning the act of reproductive human cloning Genetic Disorders More than 2, human diseases and abnormalities that have a genetic causation have been identified in the human population.
The grouped somatic cell and egg cytoplasm are then introduced to an electrical current. She has written over 40 books for adults and children. Parents with no eggs and sperm can create children that are genetically related to them. The incidence of genetic disorders expressed in the living human population is estimated to be no less than 2.
Duplicates of genes are also possible through genetic engineering and are very useful for medical purposes.
