DNA is the blueprint for life, it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles, such as plasmids in bacteria, chloroplasts in plants, and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes, and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure, its sugar phosphate backbone, made up of deoxyribose and a phosphate group are held together by hydrogen bonds and base pairs. These bases are adenine and guanine, thymine and cytosine. There are coding and non coding parts of DNA, the non coding part is called an intron, this may not seem to have a function but it helps to keep the structure of the helix by coiling, regulates when genes are expressed and is also used in DNA replication. Non-coding regions of DNA between genes are the satellite DNA, this is a simple base sequence repeated many times. It’s not all non-coding DNA though, the coding parts of the DNA are known as exons.…

In the excerpt “Ethics and the New Genetics” The Dalai Lama, also known as Tenzin Gyatso, presents to use the new arising discovery that scientists made in genetic technologies and how advanced they are becoming. He discusses how scientists are talking about being able to change the genetic make-up in produce to help those who cannot or have the advantage of having food. Another thing he brings up is how the scientists also discovered two different types of cloning. One type of cloning is therapeutic and the other is reproductive. In the Dalai Lama’s excerpt he stated that there is right time and place for when we should use these technological and genetic advances. But at the same time if we use these technological and genetic advances in the wrong way or at the wrong time it can end up being a long term consequence for our present and future society.…
Deoxyribonucleic acid (DNA) is a complex biochemical macromolecule that carries genetic information for cellular life forms and some viruses. DNA is also the mechanism through which genetic information from parents is passed on during reproduction. DNA consists of long chains of chemical compounds called nucleotides. Four nucleotides are present in DNA: Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). Certain regions of the DNA are called genes. Most genes encode instructions for building proteins (they're called "protein-coding" genes). These proteins are responsible for carrying out most of the life processes of the organism. Nucleotides in a gene are organized into codons. Codons are groups of three nucleotides and are written as the first letters of their nucleotides (e.g., TAC or GGA). Each codon uniquely encodes a single amino acid, a building block of proteins.…

Biotechnology has been the source of lots of controversy. There are those that love Biotechnology and dream of all the great things it could bring to mankind. There are also those who see it as threat to mankind, something that could possibly overthrow our current society. James Watson, who along with Francis Crick discovered the double helix structure of DNA, exerts that this controversy is not deserved. He believes that it is pertinent for our future, that it could benefit mankind. Francis Fukuyama, a professor at John Hopkins School of Advanced International Studies and author of the influential best seller Our Posthuman Future, insists that “… our compulsion to control and manipulate natural processes, including the human genome, will ultimately undermine nature itself (Fukuyama 668).” This viewpoint is concerned with conserving mankind as it is. There must be a place in between, a stance that both sides agree on.…
For a number of people, the brave new world of biotechnology promises a ideal culture where one can be free from diseases because exploitation of the genetic code. Kass argues, this idea of the future entails dehumanization, because the most important beliefs of cloning and stem cell research leads to changing the human nature so considerably, mankind would…
In conclusion, all of Kass’s objections make valid point on why cloning us unethical in our current society. The objections can be seen as premature thoughts because we are not living in the actual era of cloning. Cloning is still very experimental and we do not know all the benefits and effects of cloning. Therefore, some of Kass’s arguments can be ruled out. Even if cloning is improved and become beneficial one question that will remain is, is it ethical to…

Thesis Statement: Although human cloning is a scientific discovery of great significance which is the creation of a genetically identical copy of a human it has some medical advantages; however, it raises high debates because of its religious, ethical, and scientific disadvantages.…

For many years, scientists have been experimenting in the field of cloning. Cloning uses an egg cell and a somatic cell to make a duplicate copy of the organism. It is currently a highly controversial topic in the scientific world. Many people can benefit from cloning. From farmers to patients, not only does cloning help scientists discover more about genetics, it will also help a lot of people. However, there are also ethical issues with cloning, such as the use of embryonic stem cells and cross-species hybrids. For instance, at the Salk institute, a human-pig embryo was recently made and destroyed. The purpose of the experiment was to see if human organs could be grown inside a pig. The authors believe that we are still far off from accomplishing cloning of human organs in animals. I believe that cloning will help this world, but there needs to be restrictions on human cloning and cross-breeding.…
