DNA cloning Essay The most recent discoveries and researchesin the field of genetics: DNA cloning I am a biology major student at Brooklyn College, and of course I am interested in the most recent discoveries in biosciences, particularly in genetics and DNA cloning - Field of genetics: DNA cloning Essay introduction.

Genetic cloning essay

Nature itself is the greatest cloning agent. In about one of every 75 human conceptions, the fertilized ovum splits for some unknown reason and produces monozygotic identical twins.

Each has a genetic makeup identical to the other. Some limited experimentation has been done on human embryos. Human embryo cloning starts with a standard in vitro fertilisation procedure.

Sperm and an egg cell are mixed together on a glass dish. After conception, the zygote fertilised egg is allowed to develop into a blastula a hollow mass of cells.

This material provides nutrients to the cells to promote cell division. With the covering removed, the blastula is divided into individual cells, which are deposited on individual dishes.

They are then coated with an artificial zona pellucida and allowed to divide and develop. The experiment by Sillman showed that the best results could be obtained by interrupting the zygote at the two-cell stage. Many of these pairs of zygotes were able to develop to the cell stage, but no further.

They might well have had the potential to develop further and even mature into a viable foetus, except that the original ovum was defective and would have died anyway. For ethical reasons, the researchers selected embryos which had no possibility of ever maturing into foetuses, and thus into newborn babies.

With the exception of the sperm and egg, every cell in the body contains all of the genetic material in its DNA to theoretically create an exact clone of the original body. Most scientists had believed that such differentiated cells could not be reprogrammed to be capable of behaving as a fertilized egg.

It was fused with a sheep ovum which had had its nucleus removed. Out of attempts at cell fusion, only 29 began to divide. These were all implanted in ewes.

Cloning has had a fairly long history: It took place in, with group of scientist from the Institute for Cancer Research in Philadelphia. Cloning has many more advantages than disadvantages.

Through cloning, you could help thousands of people and animals.

CLONING WHAT IS IT Essay. Cloning is the production of one or more individual plants or animals that are genetically identical to another plant or animal - CLONING WHAT IS IT Essay introduction. Nature itself is the greatest cloning agent.

Recombinant cloning is used to further understand stem cells and the genome, similar to genetic mapping, it can be used to genetically alter the genome to what humans deem “favorable”.

Reproductive cloning is the act, or attempt, of replicating a strand of DNA to create a living life form. Cloning and the ability to manipulate and modify DNA has increased immensely in recent years. The field of genetic reproduction is creating a variety of unknown social and ethical consequences that are particular to our present time.

The Case against Cloning When I first began this essay, I held no stance on the subject of human cloning.

After my initial research, I came to the conclusion that there was no real evidence that human cloning should be illegal. Genetic Cloning Genetic cloning has become an issue in these past years, and many questions have arisen due to.
