The first two questions face anyone who cares to distinguish the real from the unreal and the true from the false.

Genetic Engineering Photo by: Proteins, in turn, are responsible for creating the traits that characterize individual organisms. Therefore, if a way could be found to transfer genes from one organism to another, creatures could be manufactured with traits that they had never before exhibited.

Based on the description of the structure of DNA provided by Watson and Crick, researchers began to search for a way to cut genes from the DNA of one organism and paste them into another. By the s, they had the answer, and the science of genetic engineering was born. It was a giant step forward.

Now, a mere thirty years later, it is possible to exchange genes between one plant and another and one animal and another. It is even possible to transpose genes between plants and animals.

No organism—from primitive life-forms, like bacteria, to higher order animals, like human beings—is exempt from this genetic swap meet. Restriction Enzymes and Plasmids The first major breakthrough on the road to genetic engineering came with work done on restriction endonucleases by Herbert Boyer of the University of California at San Francisco.

A Guide for the Curiousrestriction endonucleases "are a group of enzymes [a special type of protein] that. This recognition process involves two elements.

First there are specific nucleotide sequences [As and Ts, Cs and Gs] that act as targets for the nuclease. These are called the restriction sites. Second, there is a protective chemical signal that can be placed by the cell on all the target sequences that happen to occur in its own DNA.

The signal modifies the DNA and prevents the nuclease from cutting. Invading DNAs, lacking the protective signal, would be chopped by the nuclease.

They also have the capacity to act like a molecular scalpel, severing the DNA at exactly the spot where they detect this sequence of genetic letters. Restriction enzymes are a powerful tool because there are thousands of them, and each one acts only on a unique arrangement of As and Ts and Cs and Gs.

A second piece of the genetic engineering puzzle fell into place when it was discovered that bacteria Source: Joseph Henry Press, Under the right conditions, small, circular pieces of DNA can be transferred from one bacterial cell to another.

Single-cell bacteria duplicate when the cell divides, producing an exact copy of itself. During this process, its plasmids, as well as its chromosomal DNA, are also reproduced.

An ability to move freely between bacteria enables the plasmids carrying such genes to spread rapidly among bacteria immediately in the wake of a broad application of the antibiotic.

Some forms of E. Boyer and Cohen marshaled restriction endonucleases to cut some E. When plasmids are cut, they leave what researchers call "sticky ends," to which other plasmid segments can easily attach themselves. The point at which the pieces of the two plasmids join is cemented by the activity of an enzyme called ligase, which can be described as molecular glue, to form a stable chemical bond.

Then, the two scientists severed particular genes from another type of bacteria, one that was resistant to antibiotics, and spliced them to the sticky ends of the cut E. One big question remained to be answered.

Stanley Cohen was one of two scientists who first experimented with an antibiotic-resistant E. In other words, could genes cross species boundaries? When the bacterial cell started to multiply, the scientists analyzed each successive generation and found that they all contained the tadpole gene.

Genetic Engineering Essay Genetic Engineering, Ethical or Unethical?

The first gene transfer between species had been accomplished, and the door was now open to a wide range of similar experiments—many of them far more controversial.

It had been practically demonstrated that genes from fish, even genes from plants, could be transplanted into humans. The new technique was called recombinant DNA technology—just another name for genetic engineering—because the procedure recombined genes that originated in different organisms.

The popular media gave it another name that has been responsible for a great deal of confusion. They called it gene cloning, creating the belief that science could duplicate entire organisms, an achievement that was not at that point even distantly attainable.Have you heard?

A revolution has seized the scientific community. Within only a few years, research labs worldwide have adopted a new technology that facilitates making specific changes in the DNA of humans, other animals, and plants. Compared to previous techniques for modifying DNA, this new approach is much faster and easier.

This technology is referred to as “CRISPR. The Genetic Engineering Debate Essay Words | 6 Pages. recent discussions of genetic engineering, a controversial issue has been whether genetic engineering is ethical or not.

In “The Person, the Soul, and Genetic Engineering,” JC Polkinghorne discusses about the moral status of the very early embryo and therapeutic cloning. J. H. Free genetic engineering papers, essays, and research papers. The OEC Glossary contains useful definitions for a variety of the terms commonly used on the website and within engineering and science ethics literature.

Ethical Concerns 1. Objections to Genetic Engineering as Inherently Wrong Some people object to any tinkering with the genetic codes of humans, or even of any life form. Some religious critics perceive genetic engineering as “playing God” and object to it on the grounds that life is sacred and ought not to be altered by human intention.

Fideisms Judaism is the Semitic monotheistic fideist religion based on the Old Testament's ( BCE) rules for the worship of Yahweh by his chosen people, the children of Abraham's son Isaac (c BCE)..

Zoroastrianism is the Persian monotheistic fideist religion founded by Zarathustra (cc BCE) and which teaches that good .
